If you are a young, good looking female looking for a job in the night business, this is where you should be careful. Some escort or modeling agencies will tell you that they have a good number of employers lined-up already, but if you want to have a chance to start right away you will have to pay a registration fee or an advertising expense charge.
How to avoid: find out where the agency is located, so you can pay them a visit. Get the first job agreed and then pay the fee. If you can’t pay them a visit and they ask you to wire the money, look for something else.
