Collaborative Design Website

I need a website developer for a collaborative design contest. The site has already been designed, and outlined, the highest bidder simply needs to convert the psds to css and xhtml, and develop a backend with social networking, ecommerce, and file uploading. There will be an interface where users can upload their design in vector format, along with a jpeg thumbnail for display on the main page. A detailed page of each design will allow other members to comment, as well as download the file and reupload, all in a single threaded view. In addition to commenting, members will be able to rate each design from 0-5. At the end of each week, the design with the highest rating will be available for purchase, and will be featured on the front page. The site will require a full administrative control panel for managing featured designs, as well as moderating uploads and comments. A thumbnail of each uploaded design will be shown on a dedicated voting page, along with the five latest designs shown on the main page. An ecommerce section is required for the sale and purchase of designs, complete with cart and settings saving. Each member will also have their own profile that shows their uploaded designs and other social settings. ## Deliverables Attached is a mockup of the homepage of the site. Most of the functionality of the site can be inferred from this picture, but in-depth mockups of the remainder of the pages listed above will be provided to the winning bidder.
