Your difficulty is finding a good young person is probably a function of a lack of supply. Not very many young folks are aiming to head into that field, so no doubt you're left with those who can't find anything else.
I'm sure I'm not telling you anything you don't already know. Also, this comment isn't meant to insult your profession; I don't know why more young folks don't aspire to that sort of work.
I’m afraid it is because the bulk of our profession has chosen to outsource those jobs to Asia. Now we are an outsource company too — we do small to mid sized jobs for OEMs. But, when their product hits big — they all send the work overseas. Consequently, we stay small. But, I can’t supply the workers either. We are constantly scraping the bottom of the barrel, hoping to find a gem who can match our older workers and become the next generation of leads.
