I wish I could shed some positive light on working for airsev, In my experience working for them, all that I can say is stay away!!
Sure they pay their pilots on time, and the flying is great, that is when you fly. The maintenance is so shoddy that you spend about sixty percent of you time waiting around for aircraft to be fixed. As for the chief pilots', some of the worst "ding bats" i've had the the pleasure of working with.
As for it being a non-profit organisation, I wish somebody had informed the powers in charge who seem to be milking the system for all that it's worth.
