They seem to me like a unique operation. I applied for work with them, but regretably I was turned down because of lack of multi time. The current minimum time is: 1200 Pilot-in-Command for SE recip, 2000 PIC for ME Turbine with 500 ME PIC, also they require 100 hours of turbine experienc, a commercial license with instrument rating. I hope that will help you.
