Solar or satellite im experienced in both, but i dont know anyone who will hire me, please help!?

I live in Riverside, ca... I need help in finding a good job... I have a family now and I'm looking for a job that I can call home. But I don't know anyone who will give me the opportunity to show off my skills. I've had tons of interviews but none has called me back... I'm not great when it comes to interviews, I get nervous and I somehow lose myself while I'm talking, it gets very frustrating because I know I can do the job but like I said the interview is what kills me. Sometimes I think its who you know and not what you know, can someone help me?
