ClickBank /PHP/Perl Expert Needed

This should be a quick project for a clickbank/php/perl expert I am looking for a script that will work with Clickbank and will do what this script does: [login to view URL] We bought this and installed it but there are errors when the user is fowarded to the thank you page. Looking for sometone to either properly implement this script of install a new one that does the same. Basically we want all the features this script does. budget for this project is 50$ All bids over this will be ignored. I would like the project completed today 5/14/2009 Thank you.
