You may not be able to book with who you want to at first but there are ladies that advertise on their website "Newbie Friendly"

I would also be kind in your communications. IE No rude or explicit language.

If providers you have seen before you went away are still in the business, perhaps they will help
but not sure how long you have been away.

Good Luck

are probably the best place to start. Also when trying to build up references, keep in mind that the majority of "backpage girls" (ie providers with no web presence other than their ads), generally don't screen, have no idea who you are, and therefore are generally not accepted as references by more reputable providers/agencies. Accept the fact that you are going to have to give up some verifiable personal information in order to get an appointment with any reputable provider/agency.

Really, just get professionally verified once by one of these services and you will be golden.
I offer a $100 discount for these members, that's how much I believe in them!!
Play safe!!
