Hi Elisa,
Welcome to the forum. I don't mind providing you with advice, but I'm not going to hold your hand. If you're old enough to make this decision to go into escorting, you're old enough to do the groundwork yourself.
Before you do anything, first read the 10 point guide to starting up: http://www.saafe.info/10point.htm , then when you've understood all that and you think you're ready, that's the time to start doing outcalls from a hotel.
