Its not a good plan in my opinion. Mac sums up the chances here pretty accurately.
Whatever you do, don’t go Ag Flying.
Well, not until you are thoroughly grounded in life ‘on the land’ and understand the risks involved and accept that you will probably end your career with a list of colleagues who finished their’s while at work. Ag is not suitable for part time just to “keep your hand in”. Ag flying is as professional as any stream of flying and, since we all need to eat, will come out of this better than most.
Have a look at
AAAA Scroll trough to “Becoming an Ag Pilot”.
Have you considered military flying service? Army, Navy, Airforce, you could do much worse.
