Make affiliate program working

We have a complete affiliate software script installed and working based on the Affiliate Network Pro software from Alstrasoft. Because of the bad service Alstrasoft is giving we want a programmer which knows this software to make some small changes and to make the system working as it should be. We want affiliates to link to our site, and when a visitor subscribes to our newsletter the affiliate gets a small amount. The system should specify in the affiliate system the name and the email address from the visitor in stead of the amount and order#. We think this solution is very basic and not difficult, but we dont get any support from Alstrasoft, so we want somebody who can help us for this problem and for later to make some more changes.
