If you wish to hire a guide, Gary Bulla is well known and will put you on fish. You could also give Lee Baermann a call. He's out there all the time, and is an excellent local guide who specializes in the surf.
I see him all the time in Carpinteria, which is between Ventura and Santa Barbara.
Here's his website: Fly Fish The Surf Home
I'm not a guide, but I fish out there fairly often. If you want to meet up for some fishing, send me a PM.
