Hey George:

You might want to check out www.justaddcommerce.com. I've used Rich Media
in the past for small clients that can't afford to develop a full blown eCommerce
system. Rich Media was a little cumbersome in the past but they recently
release a new version for Dreamweaver.

Better yet, you might want to check out PayPal (paypal.com).

Let me know if u need more advise.
