Website credit card order processing

Hello all! I own a website called: procreditrepaircourse ...you know the rest (hint: .com) This site is in need of an experienced coder to make a credit card processing page and intergrate that page with verisign to proces the credit card payments. Then, once the order is successful, you will dirrect them to a page (created with a randomly genorated link) that lists the 4 downloads that make the product. That link will expire in 90 days or after 3 downloads of all four files. NOTE: I will not accept your bid unless you have previously completed a project very simmilar to this project. I don't have time to teach a newie how this is done! My budget is small but, once you successfully complete this site, I own 7 more sites that need the same work done on them so... do the math.
