Don't mean to be offensive but, what high school did you attend?
I don't want my grandkids going there- I want them to be able to spell when they graduate.
Don't know where you are located, but you might try the local union in your area. They will start you out as an apprentice.
Ask your instructor, they should be able to provide the information. Or google pipefitters- you'll get a lot of starting places.
Good luck
