Somewhat related to this so I'm piggybacking here, look into power plants. Once you're generally competent holding wrenches and understanding OSHA compliance, you can easily become some form of laborer at power plants. From there, learn everything you can about power plants while getting friendly with some in-house people and you might get yourself into Operations or Maintenance. It took years and luck, but I got in as an entry level outside operator at a bit under $40/hour a few years back; after raises and a promotion I'm now operating the on-site ZLD plant for $52/hour. Control Room Operator starts around $60/hour here. This area is expensive so these rates might be higher than you'd find near you, but I've heard of higher rates than this in some plants. The only real drawback is that rotating shift work is pretty standard.
