From what I have heard you get paid only for the days you work. Think you get paid a flat US$ rate per day of duty but once you total up your earnings - it is not that great considering you are driving heavy metal. Might have changed since then though.
I think you do tours and the company will fly you from home to where the aircraft is and you will carry on from there.
The aircraft are registered in Ghana. Crews work some very long days since the Ghanaian FTL system is somewhat relaxed to the UK version!
I think they still have a pool of pilots waiting for course start dates.
