Do K-girl bookers except any references other than provider?

Going for my first K-girl experience, tried to book with Hara recently but booker only took provider references to verify.  Been away from the hobby a looonnngg time and didn't have any to give her.  Anyone know if there are any K-girl bookers that will take professional references, etc., at least for the first time.  After first K-girl experience, I'm sure bookers will be able to verify me more easily but having trouble this first time.  I am very easy to verify through my profession and google (so I have been told) so just wondering.
