Can you do both?
I am instructing on Saturday on C-152 in one school (20 minutes drive) and on Sunday on PA-28 in another school (one hour drive).
Here in JAA land, we don't do spins anymore in the PPL syllabus, only incipient spins.
I am 38 now and have given up hope any airline will ever hire me , but I enjoy being a FI. It is very rewarding (not financially though), hence the full time job Mon-Fri.
Good luck with your career.
