No company will pay anyone for simply making an introduction.

It's up to the sales guys as well to make sure they are getting the right type of customers that will seal the deal and stay on board.

Usually the sales guy is also responsible for making sure the customer is happy beyond the sale as well, luckily adult affiliates don't have to do that / have a way to do that.
So your job is still a typical sales guy, but some parts are easier, and some parts are harder.
