php/MySQL paid membership & download site

I need a php/MySQL system with frontend and administrative backend. The system will serve as a paid membership website for digital products downloads. Integrated payment gateways : PayPal,2CO, ClickBank. Integrated Affiliate program ( Optional ). --------------------------------- Frontend ( members side ): --------------------------------- - static header and footer that I can customise, customisable left and right column , dynamic content placed in pages central area - left navbar contains both product categories ( can be managed from within admin area)and links to other pages - simple search by keyword and advanced search by category, title, author, keyword and maybe some other parameters - products listed as in shopping catalogs ( pagination ) but one product per raw and without "buy now " buttons. Every product listed with picture, description and download link - download path hidden from right-click - simple contact form ( form to email feature ) - free signup form with only few fields - members receive automatic emails on signup, renewal, renewal reminders, etc. - login form and password reminder form - free members , once logged in, can upgrade ( buy) various membership levels - logged in members can see members-only links to members pages and short personalised messages ( dynamic area placed above products listings ) - logged in members can download only products which are included in specific membership , free or paid. When they attempt to download other products they are prompted to upgrade their membership - logged in members can edit their profiles through profile form - logged in members can change password - "bookmark this site" feature - Optional affiliate area: integrated affilate script which handles all standard affiliate program features ------------------------------ Admin area : ------------------------------ - secure admin login - manage ( add/delete ) categories ( left navbar on front end ) - manage products : upload picture, add product description and download links ( I assume that download links should be handled through mysql db and [login to view URL] file in order for path to be invisible for members. Download links should probably point to [login to view URL] which then queries db so that every products download link comes from db ). - manage members : search members by date registered ,by member ID, by membership type; add / delete ( ban ) members, etc. - mass email members ( text / HTML ) ----------------------------------------------------- Other features can be suggested later. Link to one existing website of that kind which can serve as a model will be provided to chosen programmer/designer. I would like you to bid on 2 versions of this project: -version 1 : everything as described above - more complex and for me more expencive version -version 2 : without membership management system, which means only product catalog with administration part as described above. In that case I would integrate third party membership management script and affiliate management script later on. So when you bid please bid on both version 1. and version2.
