Small PHP/MySQL Tasks

I already have a membership site up and running. It is written in PHP using a MySQL database. I need some small tasks done that I don't have time to do. I would like to work with one person on an ongoing basis. I would send you the database structure and what I want done. Coding must be PHP and documented where needed. First task would be to create an affiliate report. I need to be able to select an affiliate by username, then select the month and year and get a report of how many paying members they referred during that month. ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. Complete copyrights to all work purchased. ## Platform Linux running Apache Server ## Deadline information First task to be completed by July 7th. Other small jobs will follow if I'm happy with work. Thanks.
