Unique wish granting bid site

Take a look at Swoopo, I want to use the bidding mechanism that they have, but not for the same purpose. A person will come to the web site, register for free with typical information and will need to have a credit card or Paypal account to start a "wish". This person will put in a wish from categories that the web master will build, for example - John Doe comes to the site, registers and verifies his MasterCard information. His "wish" is to play a round of golf with Tiger Woods. He is required to leave a deposit that in non refundable but usable on the site for any transaction. After the web master determines if his "wish" can be granted, he notifies John Doe that his wish will cost $25,000. If John cannot afford that or does not want to pay that much, the "wish" becomes an auction. However, the bidding is not done as a traditional auction. Each bidder will buy bids at a fixed cost (for example, $.50 each). They then put these bids against the Tiger Woods golf round. The winner is the last bid after the countdown starts (the countdown clock will be triggered when a certain number of bids are reached) or when bidding stops and the last bidder wins.(if the reserve is met). In theory, this allows a person to win the $25,000 golf outing for much less since it is a community pot. Also will do charity auctions, with the winner being a charity or an individual with a special need or wish (think Make a wish foundation). If someone really wants to win, they can put in a bid to win, which is essentially paying the posted entire amount. If a bid to win is placed, the others bidders will be credited back their bids. There must be some coder out there that wants to make something different and new?? WE NEED A GROUP THAT CAN DO VERY PROFESSIONAL GRAPHICS AND ARTWORK FOR THE SITE AS WELL AS THE PROGRAMMING, DESIGN AND SUPPORT.
