5 Custom Social Networking Modules

I need 4 custom modules created in an existing social networking site's skeleton. The layout, registration and authentication are already finished - as well as status updates and other small features (profile viewing/editing..ect). The elements I need done are as follows: -Sell files (similar to iStockPhoto) -Project Bidding (similar to Freelancer only not as feature rich) -Reverse Auction ([login to view URL]) -Tasker (Like Fiverr) -Commerical/Web store (Like [login to view URL]) This is pretty urgent, and I just don't have time to finish it myself. The deadline is end of business this Friday, so that's 3 full days counting today. When bidding please mention Friday's date so I know you've read the whole description. I can give more details via private message, thanks!
