OK this might sound a bit odd but why not recruit experienced civillian pilots. Call them special service officers recruited to fly and that is it, two week knife and fork course at Cranwell and then on to some sort of course to get them used to how the military does things. This would be much quicker than starting a new bloke with no flying experience. I would set the hour mark at about 2000 PIC. I bet you would get plenty of applications.
