[Maryland] Apprenticeship opportunities

Can anyone help me locate apprenticeship opportunities for my son, a
beginner in the jewelry industry? We live in Columbia, Maryland so
he is looking for a company that he can commute to. We are about a
half-hour from DC and 20 minutes from Baltimore.

If anyone can tell me how they got started and where he should be
looking that would be a great help.

Also, are there mentors out there that would be willing to help him?
