Affiliate Marketing function intergrate to my website

I want to my website have Affiliate network function that allows people to sign up the program and help me sell my products. They can place links, banners on their website page or use other ways to sell my products. I needs to be able to track their sales and pay them. My host ([login to view URL]) is bad, It does not provide any codes and FTP & Cpanel info & also database info. Therefore, I might use a third party or other ways. Please let me know what you can do for me. The one time full payment will only be paid AFTER the work is done and work successfully. Thank you
