Unfortunately, getting into "adult entertainment" takes more than just making a phone call dude. I actually read up about it, and here's what I found out:
The best way to get into it is to know someone in the biz. This is especially true if you are a guy. If a woman actress requests that you partner up with her specifically, then you'll get a shot at it anyway.
If they like what you do, you'll get a call back and start getting more work.
This is the easiest way to get into the industry really, so I'd recommend you start making friends with some female adult entertainers. Depending on where you live, there is usually an area or specific venues that all the top ones hang out in. For example in my city everyone knows where all the 'glamour girls' hang out and a certain type of guy will go chasing after them there..
