Getting leads is very difficult, So it would be good to start a lead exchange program where affiliates can exchange leads to their promoting programs good idea?
No, its a bad idea. Unless it has been approved by your network (and are most likely incentivized offers) you will end up getting your account banned on that network. But the odds of letting a network let its users do something like that is very very very slim. Edit: If you make $8000 a month, why would you even be asking this?
