What's the difference between affiliate and manager/middleman?

Affiliate has its uses but id rather be a manager/middleman right now, it will serve my plan much better, if someone is selling his services and has an affiliate program, can i contact him and ask him to sell his services as a manager instead of affiliate? is there any difference or downside for him?

It doesn't really matter if you're an affiliate or middleman/manager, what it matters is your % on the product. You can always contact a product seller and offer to be their affiliate/manager.

It worked the same buddy, if you are an owner of a site and you want a traffic for it, you need middle man or affiliate managers (these guys have people working for them)
