We are having a hard time finding instructors as well. Between the low regional hours and everyone moving on after 2 months and the fact where some even hire with simply a CMEL rating no one wants to instruct anymore.
My flight school recently changed the whole payscale and scheduling to make instructing a more attractive option. I hope it helps to attract CFI's because as of now my students have to book weeks in advance to even get a 2 hour block. Not very conducive to business
