Good luck to you girl!
I would suggest you invest a few dollars on a website if it will be for an agency. The rare-escorts site is decent for an independent, but for an agency, not going with your own website (could cost you about 95$ for the domain name with domain name privacy, the hosting for a year, along with a few domain specific email addresses) will not be alluring, especially since rare-escorts has an okay web gallery, but nothing suitable for more than one set of photos.
Get yourself a cell phone number separate from your own indy line, since you will want the ladies who work with you to feel confident that you are not just using their name to sell yourself.
Again good luck and we are anxiously awaiting the "Big Reveal!"
