Catalog/Database/PayPal/DigitalDownloads

I want to sell FLASH TEMPLATES throughout my site, but it just takes too long to make buttons and images for each one, so i need a database...- The project involves a simple data base system, where I can plug all the pics, data, price, info, and a few buttoms with certain features. the buttons for each Product will be VIEW and BUY. When a user clicks VIEW, it will open up that flash files in a larger screen to view! and when they click Buy it will allow the user to purchase the item through a system just like 4templates.com. - The site that i want is almost exaclty like [login to view URL] with the catgories and features it has. I have the layout and designs all done and everything I just need this "database script." When you click buy i would like it to go through pay pal, or any secure credit card thingy...lol... ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. Complete copyrights to all work purchased. - I need it to work, so that right when it is verified by paypal, it will allow the buyer to download the files automatically, i dont want alot of manual labor on my part. i just need a running automatic system! ## Platform I have windows 98, i dont know which is better for the scripts to be written in, maybe PHP or CGI, i dont know how to use them i just need it easy to upload to a server and have it work!
