Clickbank Link Security Script For Download Page

I want to create an encryped thank you page for a product I'm putting on clickbank. I want to use Clickbank's Link Security Script. You can find info here: <[login to view URL]> Is this something you're comfortable doing? Do you have experience doing this? Can I make the thank you page a wordpress page, or do you recommend I don't do it on a wordpress page? How much is your best price? Will it help if I give you ftp access to the thank you page? Talk soon, Kevin Bates
