Before accepting I suggest you read the recent threads on this Forum and the Africation AviationForum about the recent events in Escravos. Basically, it was over-run by the local villagers and the Pan African pilots and engineers were sheltering in their rooms and the hangar until the military eventually restored order. During the course of the occupation of Escravos several helicopters were damaged by the mob. $4,000 a month sounds pretty pathetic to be living under that sort of threat, whether it's tax-free or not
Even with a bit of unrest amongst the staff at Aero (as mentioned in Phone Wind's post) the pay is better than that and the other OLOG company in Nigeria, Bristow, pays a lot more than that.
