Hi good luck; follow your heart. The only hassle is HOURS and then Turbine Ones at that.
You will have to try
www.airserv.org They are based in VA USA, they might look at you to do say something like an Ops Manager & then if you get flying the flying is none to shabby good training but pay is low.
Alternative 2 is to get with a contracting company in S/Africa that has a contract with a so called NGO (those are the tree huggers) that have been trying for 30 years to get water out of a tap in Africa.
There you might "come right" if you are prepared to go through the "re schelp" of a SACAA Validation (I heard for foreigners that will stop??? But not sure, check on there website
www.sacaa.co.za
Other than that, be very sure about Africa, its a place that does not only have snakes and scorpions, it also has some very nasty things like basic if nil communications, doctors that are about on par with bicycle mechanics in Eastern Europe and roads and cars that are well ... lets not go there.
Good luck!
