Many musicians work in music stores (sales, repair, etc.), recording studios, with production companies that produce music events (sound, lights, recording, LOTS of odd jobs). There are booking agencies, photography people, radio and TV people... That should give you a start!

Consider your skills and where you might fit in. Be aware that "access to musicians" and especially, work in the public eye are sometimes thought of as desirable to the degree that people are often happy to do some jobs (like public radio deejay) for nothing or next-to. So not all of the jobs you might find would pay well.

Hope that helps.
