Tried the US/UK forces to see if they have any old canvas mess tents, they could donate ?? if they are not big enough you could put them together, and get a join put over the roof edges and take out the centre walls. Appart from that it is going to be very expensive I would imagine, even if you can get something cheap outside qatar without free cargo space it will cost a fortune getting it here. Load of old temporary offices from a construction site or camp, knock holes through the walls and build links between, might be more indestructable than a tent, and stay cooler longer.
