Mustang type / class rating will cost you approximately £17 000 at FSI Farnborough. There may be a TRTO in Germany that offers the Mustang.
Phenom 100 available from CAE Burgess Hill, similar price and contact Flairjet for work - you never know!
I doubt you will find any work at present, last I heard was Blink laying off pilots. The rest seem pretty quite on the work front.
