I debated whether to post this email or not with the actual producer's name in it. I decided that I probably shouldn't but I will give you this hint…I have sparred with him here before, which is why I got this email:
my script. He emailed a contract and then stated that I need to pay him $600 up
front against his 15% commission. I know this isn’t normal but he is a
real producer. My question is, am I getting scammed here?
Yes, you are getting scammed. No legitimate producer or agent would ask
you for a fee. A producer also doesn't ask for, or get, a commission on sales. He may have been a "real" producer once…but if he is asking you for $600, he's not any more.
