i'm not sure about conversions etc. but i would suggest that you give bailey helicopters in ft. st. john, british columbia a call. i know that they have brought a few of you down under types on an will put you to work in the oil patch, forestry, general charter stuff. they have some r44's and some nice, recent b2's among other things.
doug parrish is the CP's name and he pretty much runs the operation as far as i am aware.
