CMS programming for affiliates

We are starting a program called CMS where certain people will be able after taking an online exam with us, to sell our product. We need a back end that will be able to track how much these people are buying, if they have sold the annual minimums. We need them to be able to have a link on their websites ( click through) so that people can buy directly off internet. we ned them to be able to send customers online as well with their (CMS code ) and purchase and the system must keep track of how many boxes are sold in each of the three possible ways connected to each CMS. In addition we have affiliates who will only be able to put up ads for a typical affiliate program. we will have much more work should this be done inexpensively and timely. We would love to discuss this with you.
