Assistance with Open Cart Affiliate Program

I have an OpenCart website already in place. I need some assistance with the affiliate program that is built into OpenCart. I need it to produce an affiliate code as it is not currently doing this. I will need someone to get the cart to generate the correct code for affiliates. I would also like to have a page written with more detailed instructions on how to use the affiliate codes to market the products. Please show me any experience you have with OpenCart affiliate programs and specify your bid for this project. You must be experienced with OpenCart CMS. If you have not worked with this, please do not bid.
