I need an affiliate, referral or associate program for my website. Domain [login to view URL] Affiliates can either get paid per lead or they can choose to get paid per sale I want it to be 2-tiered. I want affiliates to have unique urls I want affiliates to have statistics and control of their leads I want an affiliate backend. Where I can communicate with them Put training videos Put a forum Put marketing materials (with their affiliate id included) They can see their stats, leads, and sales. My company handles communicating with a homeowner and gathering all of the documents necessary for loan modifications. I need to be able to track who sent the lead and whether they want to get paid for the lead or gather the paperwork and get paid for the sale. I don't know the best software solution for all of this, so if you have experience with this or know someone who does... Please send me a PM with your solution and any examples that you have done in the past. If there is a software that will do this, I am glad to use that and will pay for the installation and customization neccesary.
