Depending where you are professionally, you may have options although most will not offer the part-time option. If you've been flying for a while, you should be in a place to skip regional flying and go straight to the majors, although again, it's a full-time job and won't offer you the time off you want or the ability to live where you want (without commuting).
Corporate tend to fly fewer hours per year, but you'll generally have less schedule flexibility (when the rich guy want to travel it's on his schedule not yours).
What kind of 130 squadron are you flying in that doesn't have gouge!
