Shopping Cart with Paypal Checkout

I have two shopping cart sites, [login to view URL] and www.flyfishfly.com. There are 300 items. Both sites are done, but they dont work, so I think its time to go back to the drawing board and start over. I only want to use paypal checkout on these sites and the order must come through detailed through paypal. YOu must send me an example of what a order would look like in paypal. I want each item in our store to be indexed by the search engines. SO, if I look up wooley bugger, that is more important than the name of the site. I dont want fancy coding, i want simple, and i want it to work. I like my sites looks and feels, you could use that but the entire functionailty must be there. ie, picture viewer, etc.
