A skilled programmer once wrote a custom e-commerce customer record manager for processing credit card purchases off a website called OTT. We have had trouble contacting our programmer since he had to go to the hospital for an emergency about 6 months ago, and aren't sure what his contact information is now.
The engine had a members area administration panel, fulfillment company record export, and other goodies.
We need a new module for this system, which could process payments via credit card, electronic check, as well as a special invoice billing feature. Invoice billing is the focus. We need this module created in parallel while another programmer works on other core features of the system. Work for this addon module will not conflict with the other programmer's ongoing efforts.
