There are still many pros using film, esp. in larger formats. For wedding and portrait, check out Inside Analog Photo Radio for a very long series of interviews with wedding and portrait photogs who use film, including Jonathon Canlas. One guy shoots Super 8 B & W movies for weddings. One guy uses a Leica and Tri-x almost exclusively. Just a matter of finding clients who like the look. Inside Analog may be a sponsor here, not sure.
As others have said, it's not enough to make your work good -- which really goes without saying -- and there are LOTS and LOTS of clients who just couldn't care less but others like the look and/or the notion of something unique.
