If someone is going to represent you in modeling?
Maybe they mean to be your agent/manager and any deals that come your way will go through this agent first. They will also try to get deals for you on your behalf. They will try to mold and control your career, so you have to choose a good reputable agent.
You certainly have to be careful in that area - I have some info in that area, too large to put here if you'd like, funmail me...Take care !!
