Bitcoin Escrow System for vBulletin

For my new Project im looking for a Freelancer who is able to Code a Escrow System Plugin for vBulletin to prevent Fraud! Buyer can send Bitcoins to his Wallet Buyern can pay inside the Forum with the Bitcoins he got in his Wallet Seller recieves a Message if someone bought a Item Seller can send the Bitcoins back to his Wallet (should be Moderated, so an Admin has to Check it before) This should be a Trade-System also, for example. Buyer buys a Item from a Seller and sends money to the Wallet he got in his Controlpanel. Now he can send the Bitcoins to a "Escrow Wallet" - Admin / Seller should get a Message. Seller gives the Buyer the Item he bought Buyer mark this trade as "successfull" Now the Seller gets the Bitcoin on his Wallet Seller can send the Bitcoins to his own Wallet (for ex. Blockchain) this Feature should be Moderated by an Admin .. Im open for more Ideas .. just leave me a message with your Ideas
