Bitcoin Litecoin Altcoin Trading/Exchange Website - Repost - open to bidding

Hello i need a website where user can trade (buy and sell) bitcoins litecoins and other alt coins. also the user can deposit currency via the common payment methods. -need full api support for the website- -integrate bitcoin wallets to wordpress via rpc api- -trading script where user can buy/sell ecoins- -display trade history and current open trades- a site like [login to view URL] please ask me for more details. thank you. I would like the site to support (Bitcoin, litecoin, omni coin (new coin that will be launching in a week), namecoin, and world coin.) The site won't support fiat currencies like USD or Euros so that doesn't have to be calculated. The user will be able to post that they have X amount of whichever currency they choose (btc, ltc, omc, nmc, or wdc) and they want X amount of whichever currency for it. For example there would be two textboxes and two drop down selection choices. Textbox1 = Amount of currency for sale Drop down selection1 = Type of currency for sale Textbox2 = Amount they want for the currency they are selling Drop Down selection2 = Type of currency they want in exchange for the currency they are selling. Example: 2000 Omni coins for 0.5 Bitcoins Once they submit that order 2000 Omni coins will be subtracted from their balance and placed into escrow (a temporary sql value). If another user accepts that order then 0.5 Bitcoins will be subtracted from the users balance and credited to the sellers balance. While at the same time the 2000 Omnicoins will be added to the buyers balance. They will be able to withdraw those currencies as well as deposit them. I will have a linux server setup to handle all deposits. All the coins use the JSON-RPC protocol so that shouldn't be hard. Each user will have a unique deposit address for each coin so that it is easier to keep track of how much they have deposited. When they want to withdraw they will submit a request for a withdraw and it will show up in the admin's control panel and I will manually process the withdraw to avoid any hackers exploiting my system. If you could make it so that orders are filled automatically that would be great. For example if a seller posted an order: Selling 2000 Omnicoins for 1 Bitcoin. Then a buyer posts an order saying: Buying 2 Bitcoins for 4000 Omnicoins I would like it so that sellers order is automatically processed and then the buyers order is left with: Buying 1 Bitcoin for 2000 Omnicoins since he already bought 2000 OMC for 1 BTC automatically. Does that make sense?
