"Does anyone know how a low time pilot could get a job there in nigeria?"
By becoming a high time pilot first. Or being Nigerian. None of the big three operators or Caverton would take a low time expat.
That's not meant to be rude; all the expats are captains and therefore have to meet the client's minimum hours requirements. All the clients are oil companies (except Caverton) and therefore have high experience requirements. That aside, Nigeria is not really a place for someone with low experience to build hours.
