Unless you're going to be working as an employee or partner, your own FFL seems necessary.

You risk, of course, having your hobby become a profession with all the obligation that goes with that.

Difficult to keeps things 'fun', especially when dealing with the parade of people seeking free consulting work who tend to clutter up gun shops and impede your getting useful work done.

Good luck. We need all the good craftsmen we can get.
