Get a copy of wings magazine. In there is the publishers # Call and order the directories for fixed base operators, charters, flying schools, and approved maintenance organizations. This will give you the name and address of the director of maintenance etc. Mailing out resumes has limited results because hundreds of other guys are doing the same thing. Meet them face to face and have your coveralls and toolbox ready in the car.
There are alot of places in the lower main land.
Keep going back even though they say they don't have anything for you. Good luck
