Appsumo.com Similar Website

I would like to have a website with functionality similar to appsumo.com. [login to view URL] partners with different websites that have some form of digital product. [login to view URL] only sells one deal at a time. Frontend Requirements: 1. Offer page that has a) commenting functionality b) description c) order button (like this: [login to view URL]) - After ordering a deal, the user will be presented with text instructions on how to redeem and a unique coupon code to use at the partner website. 2. Save credit card payments via Stripe 3. Upsell product at end of checkout process 4. SSL compatible 5. Prefer to be written in PHP and all code tracked via git repo 6. My Account Page - Easy way for user to manage Credit cards, change email, view past purchases, edit default contact info. Backend 1. Easily add a new product or service and load a list of coupon codes via CSV. 2. Comment monitoring ability (delete/edit user comments) 3. Track number of sales per product/service and specify a max limit of overall sales allowed. 4. Easy 302 redirect for frontend index. For example, if a new deal is active at [login to view URL], I want to easily be able to have all [login to view URL] requests be 302 redirected to [login to view URL] (just like how [login to view URL] does it). This redirect will change weekly when a new deal starts.
