Any aircraft mechanics on here?

Do a little avionics work on almost anything. Props to jets. Private owned stuff. Started late been doing it 3 years now. Went to work for my brother he started his own shop 10 years ago or so and were keeping our heads above water some how. Kind of tuff in this economy but we wont give up. He has 20+ years in and did some manufacure's rep work on f-16's all over the world for lockheed.
