The following only applies for the biggest heli company in Nigeria. I won't quote exact figures because I can't quote the legal aspects of doing so but I guess you are in the ball park for a first year new yet experiienced cojoe at approx 100kusd p/a and approx 110k for a Capt.
This includes all travel, transport, medical, pension and a further $3000 p/a for daily food allowance.
The rest depends on how long you stay (increase 2 times per year) and is of course for working 50% of the year.
What else ?????? do you want to know????
