Civilian jobs for a Marine Corps Communications Electronics Repairman (2844) ?

I'm a comm tech NCO in the Marine Corps, but am separating because of a disability after being injured in 2006. I am still fully capable of doing my MOS-specific work, which requires me to repair radios, telephones, computers, and limited fiber optics. This separation was unexpected and I'm going to need a job to support my family when I get out in the next year. What jobs can you recommend for someone with my job background? I don't have any college experience, but have received a lot of training through the Corps. I'm putting applications into companies that the Marine Corps holds comm contracts with such as General Dynamics and Harris Communications. What other companies should I be looking at?
