I need a website with a shopping cart system, along with an admin control panel in which the webmaster can
-add/edit/delete products easily (simple, one picture per product, name, description, price, no size/color selections).
-add/edit/delete categories of products (kind of like folders to keep products in)
I also need the external shopping pages and shopping cart (just make everything in plain HTML with no CSS or any color formatting).
Please also recommend some payment processing services that I can subscribe to to use with your shopping cart. Thanks.
