hello,
just an idea to toss out: what is the logo had a symbol of a classic hollywood director's chair from the backview with the director holding out a small megaphone giving instructions on the set?

another idea: contracts, pens, handshakes and symbol that incorporates the business end of entertainment along with like a symbol of the arts (e.g. like an up to date or more modern version of the happy and tragic faces of the theater arts.

Thanks if anyone see potential in these or other similar ideas.

Here's another idea if anyone is interested:

A person (e.g. a producer) juggling, a film reel, a music note, television set, happy/tragic faces of the theater arts, a book, a computer mouse and a contract all in the air (handling it all) with the name producerbiz in a nice font/formtat. Thanks
