I don't have a specific contact, but FYI, all military working dog and handler training (all services) is conducted at Lackland AFB in Texas. I would imagine the contracting is done there as well, so you might want to start there.
I've been told that Malinois are highly spirited, very active, and somewhat more difficult to train. The Air Force (working with the Secret Service) brought a beautiful Malinois to patrol the area for explosives at a speech that President Bush gave at a local college. (I was on the volunteer committee helping with crowd control.) Gorgeous animal, but on alert at all times.
On an episode of "Breed All About It" a couple of years ago they showed Malinois and German Shepherds working as guard dogs at the Louvre in Paris. The voice-over asked, "How can you tell the difference between a GS and a Malinois? The GS is the dog that is sitting down."
There was a Malinois in my dog class, and the owner agreed that that was a good description.
