I always understood escorts spent longer with a client than half an hour to an hour, usually including having drinks and meal, chatting etc. Meeting first of all in a hotel lounge or lobby. Most escorts don't 'go out' every day, it's usually two or three times a week.
Sometimes they are taken to a function, they have to know a bit about the client beforehand so they look like a girlfriend.
Before anyone asks, no I am not an escort but have known a couple. They both worked for agencies who took a small fixed fee but looked after them quite well, providing taxis, knowing where the girls were going and having a bit of an idea about the clients. I think that is a lot safer than working independently, secretlife. Unless you have regulars, you really don't know what sort of person you'll be meeting, his sexual tastes for example.
I am really sad that you are doing this, I wish there was an easier, more pleasant way of you earning some money and fear you could be putting yourself in danger. There's no one keeping an eye on you or even knowing where you're going.
Do look on the saafe website which HirplesWithHaggis suggested.
