Customize PerlBill CGI

I have an installation of PerlBill ([login to view URL]) It doesn't work 100% as it should, and I need a few glitches worked out before their next release, if that ever happens. This invovles examining the code for an [login to view URL] callback and seeing why successful payments are returned to the system as "failed," not "paid" A few other minor mods to the code is all that need done at this time. Please only experienced PERL programmers who are quick to solve code issues need apply. ## Deliverables 1) Complete and fully-functional working program(s)including the fail:paid fix, full [login to view URL] and 2checkout functionality in executable form as well as complete source code of all work done. 2) Software has its own installer, I need a seperate directory containing identical file structure as the original install. This folder will contain only the patched files so at a later date I may install again and patch it if there were ever a problem. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform This software runs on RedHat 7.3/PERL/MySQL
