Hello, I'm looking for a way to earn money while going back to school. I'm trying to fing the names of some of the Helicopter medivac companies in the Springfield, MO area. I'm trying to get into nursing school but I'm also a helicopter mechanic(A&P) I even have some helo flight time( about sixty hours). I was looking for a part time helo mechanic job if there was such a thing. Any leads would really be appreciated. Thanks, Bell47.
