I suppose that if artlite is determined to do this then we might help with some practical advice where possible. It would be helpful to have a brief rundown of your hours/types/location or type of operations he's done to pitch any suggestions at the right level.
It would also be helpful to know the type of operation contemplated in Sudan - is it commercial charter, pax, freight or mixed? UN type or other NGO. Independent operator - missionary etc? Own support network or using someone else's? I realise you can't give names but sketch us a picture to give us an idea.
