I want to run an in-house affiliate program. I want an affiliate script I can install on my site...not a hosted solution.
I have found plenty of vendors through search, but I have never heard of any of them. Open source is always nice but I do have a budget for the right solution. I prefer C#, but PHP also ok. Only interested in MSSQL or MySQL solutions, and it must run in a hosted environment on IIS 7.
If not a direct recommendation, I would appreciate a list of must-have features I should be looking for.
