Working on production on a stage, or working as a lighting tech for a dealer for instance? Kind of different even if much of the same knowledge in common. Either would be tough under 18 and both will just get a little easier as you pass 19. It's more about connections (I guess that's networking in today's terms) than strictly age.
Cool I have contact if people in working theatres
But yeah it is the age thing
At school I do all the lighting and sound with my great techie friend
I am stage managing and running lights for a show next month
And I am also a volenteering at a local theartre group and I do their sound
But I want to expand
