Whats the best way to figure out if a Porn Star provides a PSE for us.  Does the LADirect website work?  Is there another way?  Or do I have to do a Review Search on each Star I'm looking for?  
Thanks for the help.

LADirect provides talent for porn producers and strip club headlining, and they risk losing their license if they start doing the escort side of things- so you won't get anywhere that way.

So yeah, board reviews + posts here will probably clue you in. The PS escort agencies will give you some clues as well.
