Need a reverse auction website designed and developed from the ground up

I need a reverse auction website designed and developed from the ground up. The site will let people sign up, sign in, post a job, comment on a job, and bid on jobs as well as leave a review/feedback. The site will charge bidders small fees and will require secure payment via PayPal. The site will have similar features to ‘t a s k r a b b i [login to view URL]” and “a i r t a s k e [login to view URL]” with the look and feel of “s e r v i c e s e e k [login to view URL]” and “t e m p [login to view URL]”. Project deliverables include but are not limited to database design, data search capability, Facebook like button, integration with users’ Facebook profiles, web host selection, email & secure FTP setups, site upload onto the web, site maintenance & database admin training, etc. Any bugs/errors found on the site after launch must be rectified free of charge. PLEASE ONLY PLACE YOUR BID IF: • You can deliver a website that has the same features as ‘t a s k r a b b i [login to view URL]” and “a i r t a s k e [login to view URL]” (but does not necessarily look the same). • You’ve completed at least 1 reverse auction website in the past. I will want to see at least 1 fully-functional reverse auction website in your portfolio.
