Well, for a start you want to visit the site of the Advertising
Photographers of America. I think it's www.apa.org, but I'm not
certain. Google it and you'll be on a good track.
You're shooting advertising. Advertising pays best of all types of
photography. Don't let yourself get ripped off. APA has contracts
and legal guidance on their site.
Bobbert also can tell you a lot you need to know. He might even be
in a good humor today and willing to help you out.
Look in the archives for his email - Robert G. Earnest.
