Super Simple Checkout Form

I have a small website with 3 products. Right now each product simply has a PayPal link.

I want to accept PayPal Pro right on this same website. But if possible, I do not want to setup a complete ecommerce system for it. I would just like for someone to click the Buy Now link, enter their info, hit submit and go to the thank you page.

Is there something like this available? Or would I need to get someone to custom program it for me?

You could try a 3rd party cart like Foxycart, which does just what you are describing.
