64959 Rebuild Download site

I have a really buggy download script that I want to have rebuilt. A demo of the site can be seen here: [login to view URL] I do not need a password protected admin. I will be adding a newsletter and banner system with my own admin section later. The following are the project requirements: Admin: • Add/manage categories • Add/manage products - inlcude upload of product zip file, title, description, price • Moderate payment processors, Stormpay/PayPal required. User: • Display simular to demo provdided above. • Once payment is successfull. (IPN), script will email customer with a download link. Some sort of protection of the actual file name needs to be in place. This is a custom job. Don't bother submitting reseller products.
