I also took a long break when LE was cracking down in DC area. I adopted a new handle and had to rebuild everything.
I still had contacts with some former lady friends, so I contacted them and let them know about my change in identity.
BOOK THE TIME WITH THEM. Don't be cheap, they are doing you a favor of sorts, so treat it like an investment in your credibility.
I booked time with the ladies I liked and wrote new reviews with my new handle, then asked them for white list referrals.
Dependable agencies and bookers that you previously knew are a good place start as well. I reached out to Miss Betty who I knew from before and booked with one of her ladies, that opens you up to her network of friends.
If you left in good standing with any agencies, they probably still have your contact info. (despite claims otherwise)
Jennifer's Models, Latina Courtesans, and The Booking Agent are places to start.
Ask the independent ladies on this board and tell them of your situation. Book a session with them.
Preferred411 is a great place to start. Like has already been said, pay them with a money order you pay cash for.
Take a picture of it and email the picture to them with pics of the addressed envelope. I was skeptical for a long time, but now I use them all the time. Well worth the money.
Lastly, I would not send my DL, Facebook, LinkedIn or other work info to anyone (this is me personally). If they require that, I just move on. Sure, I may have missed out on a couple of experiences, but it also opened me up to new ladies I wouldn't have seen that month.
