yes, you can allways find pilots.Thats true. There is always someone jobless on the market or someone just retired with a pension there. But 4000 us for an expat captain is too low even to atract Captains from the third world. I live in the third world so I know what I mean. 6 to 7 k will do a better job.
For an expat FO that need build up time and have some adventure in a exotic place is a good option. A couple of years will get you almost 2 k in jet and you will be ready to move to a better place.
