Ok, this may not sound great to some. If you have mechanical ability, have you considered plumbing? You don't need a degree, and you can make pretty decent money if you're a hard worker.
Company's like water works hire guys on, they ride with a plumber for 1yr at a flat hourly rate, then you go on your own and make a percentage based on the jobs you do in a day. After you've been there for 5 yrs you qualify to take the test to get your own license, so i f you ever decided to start your own business, you could.
The main guys I use in my building, make good money.
