In addition to the ideas above, you might want to reach out to organizations of other independant media creators. If you can get out to Detroit in June (in 2008 it will be June 20-22), the Allied Media Conference "cultivates media strategies for a more just and creative world [and] is the primary point of intersection in the U.S. for alternative media makers and committed social justice activists." Even if you can't make it out there, exploriong the website may give you potential points of contact.
