Just a hint: " Most legit modeling agencies do not advertise. So if you see a casting on the Internet, always submit with questions like (doesn't have to be in this order):
1. What is the name of your agency.
2. Is there a fee to model
3. Do you have a website
4. Type of jobs they have gotten models within the past month.
IF THESE CAN NOT BE ANSWERED either by email, phone or on the website then do not waste your time. There are too many modeling scams out there, too many modeling network sites that cost money to join, and to many ways you can get mixed in with the wrong people and the wrong agencies.
