I am currently in the forces and after getting to do a career in plumbing or be a electrician.I was thinking?

of doing a intensive 10wk course in either of these. Has anyone ever done one of these courses and how did you find it. I have a house and after i pass this course i believe i will prob after be a plumbers mate or something for a year to gain experience but don't know roughly how much i will be paid for being a plumbers/electricians mate till i have experience to start on my own. Any advice or information?
