I'm in LA and work at SpaceX as an engineer. You mentioned you had two aerospace companies already, not sure if SpaceX is one of them.
I would be happy to talk to you/your students. I only am where I am because of other people that helped me out where I was a kid, especially my mom who like you would, and actually still does, to find really cool opportunities like this to help me learn more about the world.
What part of LA are you located in? Maybe we can set something up
