Some equipments I first wanted to suggest (and then looked at the price) and "Stoneforge Mystic" are way beond the targeted budget ;)

I would remove "Kor Outfitter" as most of your equipment (save the new "Ogre's Cleave") has equip-costs that are lower or cost the same as the play-costs from the Outfiter. And with a single "Puresteel Paladin" on the field they will be gone completely.
If you want to go for "Cranial Plating" the I would furthermore change from "Kitesail Apprentice" to "Ornithopter"

"Scorned Villager" even works against the werewolfs, at last as long as you don't control an "Immerwolf"
In the matches I play against another werewolf deck "Kruin Outlaw" combined with "Full Moon's Rise" (and buffed up) applied more than enough pressure...say 30+ damage with a single attack ;)

As hard as it may sound, forgett vampires for bigger tournaments. For games on tournaments your local card-dealer does, their OK, but everything else, they are just not good enough. So don't put all your budget into this deck :)

I would remove "Scorned Villager" and/ or sideboard "Daybreak Ranger" for "Mayor of Avabruck" and sideboard 1-2 "Mondronen Shaman" for "Instigator Gang". Don't remove the rest but put "Instigator Gang" and "Mondronen Shaman" into your sideboard.

First, two links wich might be interessting:
My revised version of the "Vampire Onslaught" Eventdeck: http://www.mtgvault.com/muktol/decks/vampire-onslaught-revised/
My B/R vampire deck which was piloted through some local tournaments: http://www.mtgvault.com/muktol/decks/br-tribal-vampire/

Second:
Do you want to get a competitive deck, which might be able to win some games at local tournaments, or do you want to have a fundeck, to play with against friends?

I would remove 1-2 "Captivating Vampire" to add 1 more "Vampire Nocturnus" and both "Stromkirk Noble" to add 1 more "Vampire Nighthawk" and 1 "Lightning Bolt". Perhaps switch from "Olivia Voldaren" to "Falkenrath Aristocrat"

If the deck is supposed to be modern legal try to change from "Tainted Peak" to any other B/R dualland (e.g. "Blackcleave Cliffs", "Graven Cairns"). Maybe some searchlands (e.g. "Evolving Wilds") to thin our the number of lands in your deck and to activate Landfall for "Bloodghast" more often.

Some changes I would do, if it would be my deck
-3 "Bloodcrazed Neonate"
+2 "Blade of the Bloodchief"
+1 "Vampire Nighthawk"

-2 "Bloodline Keeper" and -2 "Child of Night"
+4 "Bloodghast"

Perhaps add some searchlands (e.g. "Evolving Wilds") and some more duallands

I would sideboard "Journey to Nowhere" and remove "Oblivion Ring" to get 4 more equipments into the deck. Equipment decks normally try to be rather fast, and adding control.cards only slows them down. Furthermore there is a high chance of having to many creatures, who wants to get equipped, on your hand, but not enough equipment.
Stock up and sideboard "Journey to Nowhere" and take a look at "Dispatch" wich might be a good replacement for it.

Some suggestions, based on my monoW Kor equipment deck (http://www.mtgvault.com/muktol/decks/monow-kor-equipment/) and my monoW pauper equipment deck (http://www.mtgvault.com/muktol/decks/monow-pauper-equipment-2/)
Cranial Plating ({2}; {1} to equip; Equipped creature gets +1/+0 for each artifact you control), Swiftfoot Boots ({2}; {1} to equip; Equipped creature has hexproof and haste), Infiltration Lens ({1}; {1} to equip; Whenever equipped creature becomes blocked by a creature, you may draw two cards), Vorrac Battlehorns ({2}; {1} to equip; Equipped creature has trample and can't be blocked by more than one creature), Sylvok Lifestaff ({1}; {1} to equip; Equipped creature gets +1/+0. Whenever equipped creature is put into a graveyard, you gain 3 life), Leonin Scimitar ({1}; {1} to equip; Equipped creature gets +1/+1)
Ornithopter ({0}; Artifact Creature; 0/2; flying)

The idea to place +1/+1 counters on your vampires and then proliferate is basically a good one, but don't forgett your opponent. Most modern decks today consist of ~1/3rd spells, from which many are removal (point/ mass) spells. Your opponent will try to remove as many of your creatures a he can, thus proliferate will often be played for only 1-2 creatures. If you have 5+ creatures out, then you should be able to win, even without proliferate.
An alternative to "Rakish Heir" could be "Curse of Stalked Prey". You loose a blocker, but the curse comes earlier and is harder to remove.

I would change from "Child of the Night" to "Bloodghast" ({B}{B}; 2/1; Bloodghast can't block; Bloodghast has haste as long as an opponent has 10 or less life; Landfall: Whenever a land enters the battlefield under your control, you may return Bloodghast from your graveyard to the battlefield) and maybe add some searchlands (e.g. "Evolving Wilds)

Furthermore I would remove "Blood Tribute" for the following reason: Without acceleration it can't be played earlier than turn 6, thats if you start with 3 lands in your hand and draw 3 additional lands until turn 6. Until that you will allready have attacked your opponent and removed a great deal of his lifepoints, especialy if e.g. "Vampire Nocturnus" comes on turn 4 and activates his ability, or you have a flipped "Bloodline Keeper". Let's say you have your opponent down to 12-14 lifepoints and you play "Blood Tribute": You spent cc6 on a spell that removes 6-7 lifepoints and are not able to play anything else this turn. Even a "Shock" has a better mana/damage ratio. If you want to keep it, sideboard it, and use it against e.g. lifegain decks, or decks which hide behind some defenders you have trouble getting through.

As for the sideboard, I can only tell you what I'm using in my B/R vampire deck (http://www.mtgvault.com/muktol/decks/br-tribal-vampire/)
Your sideboard will depend on the decks you play against and have troubles.
"Glaring Spotlight" against hexproof
"Leyline of the Void" to shut down graveyard based decks
"Dual Casting" to copy some spells
"Evil Presence" to disturb my opponents (multicolor)manabase
"Electrickery" massremoval
"Bonfire of the Damned" massremoval
"Shattering Spree" artifact removal
"Vampire Hexmage" e.g. Planeswalker removal

Some suggestions, based on my G/R werewolf deck (http://www.mtgvault.com/muktol/decks/gr-tribal-werewolfs-2/)
Mayor of Avabruck ({1}{G}; 1/1; 3/3 when flipped; human/ werewolf lord)
Instigator Gang ({3}{R}; 2/3; 5/5 when flipped; Attacking creatures you control get +1/+0; +3/+0 when flipped)
Young Wolf ({G}; 1/1; undying)
"Brimstone Volley" could be replaced with "Searing Blaze"

You asked for my opinion, and here it is: The mana-curve is not real good and goes just the wrong way. I would assume that most (fast) decks will overwhelm you before you get into play.

The changes I would do:
- 2-3 Lashwrithe ...4 times seems a little bit too much as finisher. This deck also looks like it wants to win by overrun, and not with a single, strong, finisher.
- 2 Bloodline Keeper ...4 times is a little bit too much, also he has the same cc as Vampire Nocturnus, which should always be favoured
-4 Child of Night ...there are better vampires. See suggestions
-1 Vampire Nocturnus ...also a finisher, so 1 on the battlefield should be enough.
-2 Feast of Blood ...good spell, but in the matched I played with my vampires, i often enough couldn't cast it because my opponent shot my vamps away. For alternatives see under suggestions.
-2 Read the Bones ...I would use Sign in Blood over Read the Bones, because it's cheaper to cast, and can be used as finisher. I doesn't dig that deep, the Scry effect is missing, but in a monoB deck it shouldn't be a problem to get Nocturnus to activate.
-5 Swamp ... -1 swamps (22 mana should be enough for aggro) and change 4 swamps to a searchland e.g. Evolving Wilds (Verdant Catacombs if you want to invest ~200 bucks)
- 14-15 cards

+1 Sign in Blood
+2 Tragic Slip ...one of the best removalsspells there is. Most decks consist of ~1/3 instants/sorcerys and most of those are removal spells. So there's always something dying, which you can only profit from with this spell.
+ 2-3 Shadow Alley Denizen ...good onedrop, that allows your vampires to slip through your opponents defences (If you don't play against another black or artifact deck)
+ 5-6 cards

Suggestions:
Blade of the Bloodchief ({1}; {1} to equip; Whenever a creature is put into a graveyard from the battlefield, put a +1/+1 counter on equipped creature. If equipped creature is a Vampire, put two +1/+1 counters on it instead), Æther Vial ({1}; At the beginning of your upkeep, you may put a charge counter on Æther Vial; {T}: You may put a creature card with converted mana cost equal to the number of charge counters on Æther Vial from your hand onto the battlefield), Mimic Vat ({2}; Imprint -- Whenever a nontoken creature is put into a graveyard from the battlefield, you may exile that card. If you do, return each other card exiled with Mimic Vat to its owner's graveyard. {3}, {T}: Put a token onto the battlefield that's a copy of the exiled card. It gains haste. Exile it at the beginning of the next end step.), Bloodghast ({B}{B}; 2/1; Bloodghast can't block; Bloodghast has haste as long as an opponent has 10 or less life; Landfall — Whenever a land enters the battlefield under your control, you may return Bloodghast from your graveyard to the battlefield), Vampire Hexmage ({B}{B}; 2/1; First strike; Sacrifice Vampire Hexmage: Remove all counters from target permanent)

Enchantment decks normally try to be a little faster than this deck. They use hexproof creatures and cheap enchantments.
Starting with cc2 in your mana-curve, and having no ramp, is seldom a good idea.

Some suggestions, based on my G/W pauper enchantment deck (http://www.mtgvault.com/muktol/decks/gw-pauper-enchantment/)
Gladecover Scout ({G}; 1/1; hexproof); Silhana Ledgewalker ({1}{G}; 1/1; hexproof; can only be blocked by creatures with flying or reach), Slippery Bogle ({G/U}; 1/1; hexproof)
Ethereal Armor ({W}; Enchant creature; Enchanted creature gets +1/+1 for each enchantment you control and has first strike), Forced Adaptation ({G}; Enchant creature; At the beginning of your upkeep, put a +1/+1 counter on enchanted creature.), Hyena Umbra ({W}; Enchant creature; Totem armor; Enchanted creature gets +1/+1 and has first strike), Rancor ({G}; Enchant creature; Enchanted creature gets +2/+0 and gains trample. When Rancor is put into a graveyard from the battlefield, return Rancor to its owner's hand), Spider Umbra ({G}; Enchant creature; Totem armor; Enchanted creature gets +1/+1 and has reach.)

I would use 2-3 "Read the Bones" instead of 4 "Drown in Sorrow". You should have enough discard so that your opponents creatures will be no problem. But without carddraw, you will land pretty fast in topdeck-modus. Carddraw works a little against "Ensnaring Bridge" (which I would play only 3 times, as one should be enough on the battlefield) but if you don't have answers to threads your opponent might draw, then it will be a loss. A card you could take a look at would be "Extirpate" / "Surgical Extraction", if not maindeck then at least sideboard.
With that low mana-costs you could also try to lower the number of lands by 1-2 (Works against "Raven's Crime", I know)
"Pithing Needle", "Persecute", "Dark Withering" (Should work like a charm with Liliana), "Scepter of Fugue" and "Bitter Ordeal" could be sideboardoptions. Maybe "Evil Presence", if you're up against multi-colored decks which relly heavy on duallands.

Forget resurrection-spells in aggro, you need the slot for...aggro ;). An option could be hexproof equipment, if you're up against decks with many removals.
Personally i don't like "Dark Ritual", but thats because I built an play my decks under modern restrictions, and don't like to see that a deck, which would be modern legal, messes this up with a single (though good) card.
If you want mass removal, take a look at "Electrickery".

Try a 2/2 spit between "Pulse Tracker" and "Guul Draz Vampire", should give you some options to attack and some very cheap finishers.
I think it will depend on how good the carddraw will work, if you stay with "Kalastria Highborn". If you get enough cards in your hand, you have many options to play, but will need the mana for those.
"Devour Flesh" (and also "Gatekeeper of Malakir") depends on the deck you're plaing against. Goblins? Humans? Tokens? Creatureless? What does 1 creature more ore less mean. Green? Angels? That will hurt. Personally I would try a split between point-removal and sacrificing effects and maybe sideboard the other card.
I made the experience that either you get a bunch of vampires out and win the game regardless of your big finishers, or your opponent removes to many of your vamps, or just hinders your play (Counterspells, "Propaganda" or "Ensnaring Bridge" (That was one horrible game...))

Some suggestions, based on my G/W pauper enchantment deck (http://www.mtgvault.com/muktol/decks/gw-pauper-enchantment/)
I would change from "Akroan Skyguard" to "Silhana Ledgewalker". She won't get +1/+1 counters for every new aura attacked to her, but has hexproof and is thus harder to remove. Furthermore "Avacyn's Pilgrim" to either "Gladecover Scout" or "Aura Gnarlid"

If you want to work with aura-ramp I would suggest using "Utopia Sprawl" or the cc2 variant "Fertile Ground" instead of "Abundant Growth", which does generate any type of mana you want, but no additional mana. Perhaps add either some duallands or some searchlands.

On the Aura side I would change from "Holy Strength" and "Wreath of Geists" to "Forced Adaptation" and "Hyena Umbra"

Some suggestions, based on my G/R land destruction deck (http://www.mtgvault.com/muktol/decks/rg-control-land-destruction/)
Trinisphere ({3}; As long as Trinisphere is untapped, each spell that would cost less than three mana to play costs three mana to play)
Magnivore ({2}{R}{R}; */*; Haste; Magnivore's power and toughness are each equal to the number of sorcery cards in all graveyards)
Utopia Sprawl ({G}; Enchant Forest; As Utopia Sprawl comes into play, choose a color. Whenever enchanted Forest is tapped for mana, its controller adds one mana of the chosen color to his or her mana pool.)
Darksteel Citadel (Land; Indestructible)

LD spells:
Boom // Bust, Creeping Mold, Roiling Terrain, Stone Rain

Some changes I would do:
Reduce "Kalastria Highborn" by 2-4 and add either "Blade of the Bloodchief" or "Blood Artist". The drawback on Kalastria is, that you always have to keep one ore more {B} free to be able to pay for the effect, which might slow your play.
Reduce "Pulse Tracker" by 2-4 and add "Guul Draz Vampire". Normaly a card that I woudn't play in a vampire deck, but if you manage to play fast enough, they can be a real pain in the ass.
Change from "Ultimate Price" to "Terminate". You don't have target restrictions, and the target can't be regenerated.
Change from "Magma Jet" to "Read the Bones" or "Sign in Blood". I think that this deck will need some carddraw as your hand will be empty pretty fast. Advantage of "Sign in Blood" is that it can be used as finisher (2 damage), "Read the bones" digs deeper.
Maybe add 4 more duallands, to make shure you are able to cast 1-X red spells when you want to.

Some further suggestions
Madcap Skills ({1}{R}; enchantment; Enchanted creature gets +3/+0 and can't be blocked except by two or more creatures)
Tragic Slip ({B}; target creature gets -1/-1, Morbid: Target creature gets -13/-13)
Bump in the Night ({B}; Flashback {5}{R}; Target opponent loses 3 life.)...black alternative to "Lightning Bolt", but player only
Vampire Nighthawk ({1}{B}{B}; 2/3; Flying; Deathtouch; Lifelink)...maybe an alternative for
Evil Presence ({B}; target land becomes a swamp)...sideboard-material, can really mess up your opponents mana-base

No, no tournament expirience with this one, sadly I don't have the time to test all those decks I built on tournaments. They are played on Magic Workstation in mirror mode (against the same deck) and against some other decks, if I get the time. They all should work, but the fine tuning might be missing :)

I tried to keep it cheap, the only expensive cards I suggested where "Warren Instigator" (~$7) and Legion loyalist ($3.5 , I think it will dropp when out of standard) ;)
The cards that make 60% of the price of my deck are "Purphoros, God of the Forge", "Nykthos, Shrine to Nyx", "Legion Loyalist" and "Warren Instigator". Add Krenko, and you come up arround 70% of the vallue
