In the SF Bay Area there are
VO gigs listed under Gigs - Talent. Usually one or two a week - some pay a little and some are no-budget. From time to time there's a job listed under Community - Artists.But the best section to check is Jobs - TV/Film/Video - those listings in this section are paid postings and cost $75. So if someone is paying $75 to find an actor, you know they'll have a budget for the job. I landed one there about 6 months ago that paid union rates. They said they didn't want to pay the 20% commission to an agent so they posted on CL. I gave my agent their cut but it came from my pocket rather than the clients.
I know a number of folks who have landed a gig on CL that turned out to be quite lucrative - one freind got a gig for Chevron and has had tons of repeat business from it
