Amazon Hot Trends Website

I need a fully prepared to launch website for Amazon trends analyses (sales website with design, members area page, billing system), which would show, what kind of products are becoming popular in Amazon (by using bestsellers, hot new releases pages of each products category, or other ways). Website should have automatic members area, which can be similar to this website (see video): [login to view URL] Customers must be able to pay with paypal (monthly subscription) and get instant access to the website members area. Website system might be unique, as well as customized open source system. The analyses script must be compatible with standard shared hosting [login to view URL] requirements and not use too many CPU/RAM resources. Website must use Amazon API to ensure stability of a whole system. All bidders must send a detailed features list for this project and write, what their script exact functions will be.
