Auction Script - Similar to GetAFreeLancer/Ebay

I am looking for an auction script where users can sell their Myspace accounts on. The site will be similar to getafreelancer.com. Users will create accounts and post auctions for their myspace accounts theyre selling. When someone is posting an auction the feilds that will need to be filled in are: 1. amount of friends. 2. amount of profile views. 3. Myspace URL Picked? (Check Box Yes or No.) 4. Average requests per day. 5. Additional Information. The listing should be listed on the homepage or a recently added section else where an also be added to the appropriate catagory. The catagories go by the amount of friends on the users myspace account theyre selling. The first catagory should list all accounts from 1-1000 friends. Second catagory: 1001-5000 friends. Third: 5001-10,000 Fourth: 10,001-20,000 ...etc, etc, all the way up to 100,000+ friends. Others members will bid on the myspace accounts and the highest bidder wins. Their should also be a messaging system where users can talk to eachother through the site (similar to getafreelancer but users should be able to message eachother without having to make a bid) many keywords will need to be filtered out like anything that deals with contact information. The payment system should also be similar to getafreelancer. The seller will have to give up 8% of their earnings as a fee, and the buyer will have to give up a certain amount which will range with the total amount of money. (example: total money = $.01-$5, fee will equal $2. total money= $5.01 - $10, fee equals $4..etc.). Paypal will be used to deposit money into the users accounts. Their will also need to be an escrow payement type. The rating/feedback should be similar to getafreelancer where users can rate the buyer/seller on a scale of Postivite, Neutral, and Negative along with a comment. Another section to the site will also be needed which will allow users to post projects for myspace help. This will be almost exactly like getafreelancer. The users will post projects for myspace help such as custom layouts that need to be built, custom codes that they need written, and any other requests they have. I will need an admin control panel where I can edit users: -add -remove -edit info -read personal messages for each project they posted/bidded on -ip banning -edit/delete/add feedback and rating Projects: -edit -delete -remove Pricing: -edit seller percentage fees -edit buyer fees I should be able to edit any aspect of the site. If you have any other questions please ask.
