Creating LIVE Online Auction + User Login + Adv Item Search

I am currently looking for someone that can develop a couple of scripts that I can use to startup a simple online auction like [login to view URL], that's not my site, but I would like something very similar. I can easily see this project to extend way over $750, this is only about 1/3 of the complete projects. I split my project into 3 phases, if the first fails then I will you pay you for how much you have accomplished. account - display number of bids available to use - e-mail box - support e-mail message - create account form (name, email, username, password) secure code, unhackable manual insert bids bought into account graphical designer, simple yet attractive decide html, xhtml, php code [login to view URL] auction - current time, time extended when clicked - number of bids, bid history - price of item, changed number - watch list (area that displays each item watching in box) - identify winner when time ends and stop bidding search - item displays - photo display - product filters (price, time left, number of bids, date ends, etc) - categorizes products are able to minimize subcategories - photo gallery payment - shopping cart for buying bids (3% fee +.30 paypal fee) auction database - log all bids (who, how much, which item, winner, date)
