Shopping Cart Custom

Okay this shouldn't be TOO hard, and im sure there is already a prebuilt cart for this, but this is the features I need. These are a MUST! - Affiliate program built in - Linkpoint Connect (API, Central) - Paypal - When price is 0.00, skip payment method, and complete checkout - User login to view orders - User names, for example when user logs in, should say Welcome $user, and so that I can add a url for there report to [login to view URL]$user ($user, of course being automatically populated to their username - Admin backpanel (of course) - No shipping neccessary - MOST IMPORTANT PART **MUST HAVE A FORM ACTION FOR AD TO CART. for example, form1 name, form2 website address, form3 keywords, then order, and while order is processed should say this information. - Reports menu on the admin, at least to see sales from such date to such date - Email function to email all members, and affiliates email - Must have affiliates log in, to see stats, and beable to copy banners A LOT OF THESE FEATURES CAN BE FOUND AT [login to view URL] (which we presently have for our shopping cart, but some of these above included features do not work. Thats about it, like i said most typical carts can have this. total products are only like 15, no need for any type of store front, will need custom templates, and these can be plain templates, and I will intergrate it in to the site
