I recently purchased a license for software called AgilBill. This a PHP/MySQL billing program that has powerful (complex) logic that allows for a variety of billing requirements, such as those required by ISPs.
I need someone to help me analyze my business needs, create a requirements document, and then create a functional and technical specification to customize this software so that it will do what I need. Please bid based on the assumption that this project will take you 50 hours.
I'm looking for someone I can work with over the long run. In other words, this will be a test project. If it works out well, I estimate that I have 25-50 hours per month of coding that I need done on an ongoing basis.
