Encrypt Payment Buttons On My Site

I have about 200 products with PayPal Buy It Now buttons that all need encrypted so that when someone goes to my site, they can't just read the source code and get my products for free. This would only take about one day, I just don't have the time or patience to do it on my own...not with a baby coming at any time! I have tried to encrypt entire pages, but for some reason, it just doesn't want to work that way. When I save changes, the entire page is blank...there's just nothing there. So ~ This is for PayPal Button Encryption (each is individual since each one has a confirmation page to the specified product download) ONLY AMERICAN OR CANADIAN BASED COMPANIES/INDIVIDUALS!!!! I prefer an individual as I think that the little man always deserves to earn respect by starting somewhere.... Good Luck on Bidding!
