Without seeing your resume, I'd definitely draw as little attention to it as possible. They want to see full time pilot at the interview. After those 20 minutes, they truly don't care (and they really can't care since you're probably protected by the union and can bid reserve or whatever to focus on your business).
Perhaps instead of saying you own Bob's Aviation---say you work for Bob's Aviation, where you've learned great customer service, teamwork, and CRM in a challenging and dynamic environment and had great flying experiences as well. Then, when they to do your background check, have your wife pick up the phone and talk about what a swell employee you are and how you also volunteer for the company charity events.......
All true and pretty good story as well.
