Artlite,
Did you mean you have been given 2-3k Euro of the companies money to spend on stuff our you are spending "your" money on things to take?
South Sudan isn't a place I wouldn't want to be right now. If you haven't noticed there is a region type conflict going on between South Sudan and Sudan. All the oil in the South and the North isn't happy about losing control of it.
Unless they are paying a huge monthly salary and can give you iron clad assurances of your safety I would walk away from this gig right now.
