I've never done harvest, but I CAN say, with complete and utter certainty, that it's alllll about who you know, who you meet, how much they trust you, and things like that. Harvest in NorCal and whatnot is becoming an international phenomenon; i.e. travelers from all over the WORLD go to that area, trying to secure trimming work, either by literally flying signs with fiskars on them, hitching up and down the coast, asking every single blessed soul who gives them a ride, or occassionally even posting shit on CL about it. You have much, much MUCH competition, my friend, thats all I can say. Not to discourage ya, b/c I'm all for living the dream, but... go out to NorCal/OR, and start networking your little ass off. Otherwise, it seems mostly an 'insider' industry; other than pot, that area of the country doesn't have much of anything going for it, and so the locals tend to employ people they personally know and trust to do things like that.
But then again, I could be wrong.
Anywayz. Welcome to the boardz. There might be more appropriate places to ask questions like that, though..
