You've got an adorable look and you picked a great time to get started in DC. If you're safe, real, and perform, you'll do well! But you need to earn trust. Can I tell you a couple of tips to help you do that? If you don't think it's too pushy of me? Reviews will help you a lot, but you have to do a couple of things first, and the good news is it is is easy and free.
(1) Get a free email account (like gmail, yahoo). You need the email so you are in a better position to communicate with prospective clients, esp. to receive the information you need to screen them. A phone # isn't enough to handle the job. Eventually, you will also need to provide references so that other providers can screen; one hand washes the other. So an email address is essential for that.
(2) You need a website (try escortfiles.com or similar) so you can link to TER and so you can post your ads on the TER ad boards (also free). Best marketing ever. The TER link goes right on your homepage. The website is easy to set up. It will not take even a half hour to do it and upload your pics, etc. Once you have the email and website, one of these guys may TOFFT and you'll land that coveted first review, and the rest is up to you
Your choice how you do your business, of course, but I don't think these tips will hurt you a bit. Good luck, stay safe, have fun! :
