E-commerce site for digital goods (zip and pdf downloads)

I will need an e-commerce type shop where users can buy and download digital goods (.zip and .pdf files). The site must have the fallowing: - user authentification (user opens account, must sign-in in order to download); - credit system: the user will have to buy credits prior of buying (he will access the payment page where he will buy credits through different payment methods). - all the articles will have the price in credits. - admin panel where the admin can upload the files on-line and have different options (title, price in credits, description, date and hour when the product will appear on-line etc); - he will have the possibility to open a project (let's say "paper25102006") and to upload to this project different files. When he finishes the project all files inside the project will be zipped and become available on-line. - different statistics (users signed up, credits used, files downloaded etc) - security features (when the user will download a file, the credits will be deducted from his account and he will receive an unique url to download - [login to view URL] - link that will be available only until he downloads the project once, once he finished downloading the file, the link will no longer work. And other small features to be added. THE PROJECT MUST BE PARTIALLY COMPLETED UNTIL MONDAY (a working beta version) and fully completed (with testing) in 2 weekd time tops. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
