I'm a touring musician. Usually out a week or two per month and most weekends.
I suggest looking into Airports, especially General Aviation line work.
It's an easy field to move up in as well since aviation management is primarily based upon experience.
I went from working the line to director of operations / management and make double what I did when I started 2 years ago.
It's an exciting field that allows you to deal with something unique everyday, Plus you get HUGE tips from professional pilots...
