Hi
motherof 3+2+2 
I live in Northern California but I can't think of any resources other than Job Corps or California Conservation Corp, sorry.
In your post I see a lot of what he won't do, I'm wondering if there is anything that he's willing to do that you can build upon? Unfortunately, if our children are not willing to take steps to help themselves, there is not much we can do for them.
I'm so sorry to hear that he has tried to kill you in the past, that he is not kind or safe with your younger children, and that he still scares you even though he seems to have better control of his temper. I completely understand not wanting him in your home or too close in proximity.
