Never, ever, ever pay for a meeting or audition. Yes, take classes and pay for them, fine. But if a "modeling agency" contacts you asking to come to an open call (with a check in-hand), ignore them.
When I was first starting out, I had a woman contact me from a modeling "agency." She had this weird, put-on arrogance to her when giving me details. When I asked her if there were any fees associated with the meeting, she gave me a convoluted response (as these places often say they're "free" but make you pay them for headshots and such).
I said I'd have to give it some thought, and she hung up. What a professional "agent" ...be careful
