[Fmpro] broadcasting rates and rights

[GIORGOS KOLIAS]

Hello everybody,

Although I never posted anything on this "mechanism" before, I 've done some reading on previous issues discussed here but this is my first posting. 

I've been composing music for the past 7 years, for small productions especially theater, off and off off Broadway. Recently I have received an offer to write the music for a documentary. The project is a low budget production yet it has potential to go big. My question is what should I do to get  a cut from the earnings in case this project goes really well, that is, better than expected. I am not union, and I haven't signed a contract with the production company yet. What is usually the procedure and how does a composer usually gets paid (and how much) from broadcasting if he is not in a union.

I hope any of you could help me.

Thanx in advance,
Giorgos D. Kolias
