Artistic professions?

Hello, I'm currently a student and hobby producer (of electronic music). I've been seriously considering a career in music. The ideal scenario would obviously be to become a successful producer, but that's not realistic. What other options are there, with or without a high school diploma, if I want to stay on the musical path?

I've heard of audio engineering or sound technology. But is that a safe path? I'd love to work in a professional producer's studio or prepare the equipment for festivals. What do I need to learn now to be well prepared later? Is it really that difficult to find a job here? How musically gifted do I need to be to get a foothold here?

Thanks for all the answers!
