Hi Mohammed,
Welcome to the forums. The least expensive program that I know of interneka.com/ for 149. I can't verify how good it is, but have heard some decent feedback. You can probably find cheap or free software or scripts but do they work and will your affiliates trust it? The savvy affiliates, the ones that you really want as partners are reluctant to work with companies that don't have good, well known tracking solutions in place. I personally would not launch a program unless I could afford to go with one of the programs affiliates know and trust like myaffiliateprogram or Directtrack.
That's my 2 cents. Hopefully some affiliates will come by to give you their opinions also.
Best of luck!
