I have been thinking about starting up an upload type website. Where users can register an account and have a subdomain like (mikefro.uploadIT.com) or whatever and then they have an option to create different types of categories for uploads (like images, docs, scripts, etc..) so the links would look like mikefro.uploadIT.com/images or mikefro.uploadIT.com/docs something like that (uploadIT.com is not mine just a domain I thought of).

Maybe that would interest you? although a traffic wholesaler sounds like a much more exciting job then mine. I'll see if I can think up anything else.
