By far and away, your best bet is to check with Volunteer Lawyers for the Arts. A group that specializes in this sort of thing. If you contact a nearby office, they should be able to find a lawyer or law student who can help you. In my experience, a member - or the boss or professor of a member - can make a phone call or write a letter and set things right in a matter of minutes.http://www.vlany.org/legalservices/vladirectory.php
Best of luck and have many future great shoots!
