Go and get an Ag. Rating. Cost you about 18k. Then go mixing for awhile to learn the industry. If you are any good at that and keep your nose clean within in 18 months you will be flying a turbine with a rating you didn't have to pay for, flying upwards of 600hrs a year and getting paid well over 100k a year. There is a huge pilot shortage in the Ag. Sector at present and new blokes are getting turbine seats with only 100hrs of experience, some even less.
Be warned tho, Ag is not for everyone and these good conditions will only last til the next drought.
However it might be worth looking into, at least the return on your investment is better than instructing.
You will have to leave the big city tho.
