Ad Supported Auction Site

I have a unique model for an Ad Supported Auction Site. It must include a professional front end with live countdown auctions, a nice logo, and other images that you will need to create. The secure back end will store customer information and efficiently process many small credit card charges, each time emailing new information to customers. The site [login to view URL] is a good reference as to the sort of technology required although my site should be more simple and professional, with less active traffic and little real time information, fewer animations, and no multimedia. Please send me a portfolio of your prior web design work along with your bid and explain what makes you better than the competition. I will pay a price between $250 and $750 when I receive your your completed work and I am satisfied with the quality. I will also provide a very generous bonus once I get good consistent results (revenue) from the site.
