Online Shopping Solution for SharePoint 2010

Online Shopping Solution for SharePoint 2010 We would like to let develop in c# for the SharePoint Platform 2010 and SharePoint Foundation some ecommerce functionality which could be used under SharePoint. The main idea is to have s commerce site template/definition/Solution whatever with web parts, which allows any SharePoint user to see the products/items, to add them to a basket, to check out, to continue shopping, and to pay with Credit Card or PayPal. Some Must Have Features: 1. An Items List with all the details, price, item, description, thumbnail, etc. Product pictures can be uploaded and automatically resized to a thumbnail size. 2. The items are listed in different views on the Site (nice presentation of the items) 3. Add to basket function: with the total and sum of the added items in the basket. 4. Continue shopping feature 5. Checkout feature 6. Summarize shopping items, with the total and Taxes ect. 7. Payment with the customer delivery address and billing address 8) New clients must first register, then can pay with PayPal. 9. Confirmation and order, and invoice send as an attachment 10. Confirmation Email with the summary of shopped items 11. Customer has login and can see any time his shopping history 11. Some Admin Features like Reports and billing 12.
