Background: Okay, there is a company out there which provides materials, support, etc for a certain field. They also provide websites, which are obviously NOT created by someone who knows what they are doing. I have had to try to make improvements to one of these websites, so I have an intimate knowledge in what they lack. Basically they provide hosting and some content for people in the field, for a reasonable fee. However, I think the websites themselves do not produce the results that they should.
I would like to propose to this company that they offer the option of custom website creation (that would work with whatever content generation system they are using) to their members. My company would provide the design services and give them a percentage of our fees. Also, their company would continue providing the hosting and content. What I am wondering is how much should I suggest they would get as a commission? Also, do you have any advice on how to go about suggesting this? At least I do have a contact, but I have never made a similar proposal and am not exactly sure the most professional way to do so.
