eBay style auction website - engine only

The project is aimed at a specific audience: selling one category of products. This project should be a piece of cake for someone who's familiar with PHP coding and has some time. In fact, I could do it myself but I'm lacking the "free" time. So, here is what's all about: 1. User must register to post auction 2. User can receive feedback after end of transaction 3. Everyone can search for items but can only place the bid once registered and logged in 4. Users can communicate via built-in messaging system (ie. private messaging) 5. Auction must contain description, payment method, shipping fees, pictures (up to three) 6. Seller will be charged for insertion fee 7. Auction due date is 30days maximum 8. User are being notified if they were outbid or if they won the auction 9. Insertion fees must go into my paypal account which I will set up later 19. Item will be listed only after payment has been sent to my paypal account for "premium auction" 20. Free listing option should exist but auction due should be 12hours only for "free auction" 21. Site admin can see all user details like feedback, their email and all their present and past auctions, can see their home address, telephone number, can delete their accounts, rename accounts and so on 22. User can edit their listing, change pictures, description, price and shipping method if they listed using "premium auction" only 23. Users can end their auctions early 24. When creating a listing, following fields should be available: auction title, item condition (used or new), starting price, reserve price, item description field, 3x picture fields, shipping fees and return policy. Please contact me for further details. I want the engine only, the rest could be plain HTML and CSS if desired. Bidders should have their own hosting solution already as I won't provide it. If you accept this project and I like your work in progress you could end up earing $100 more!!!
