A109 Type Rating
You do not mention which model of A109 you wish to be type rated on, this will affect price and future hire. It will be cheaper to train on and hire an older model (A109A, AII or C model) and you may have to source the aircraft and pilot separately as most companies at present do not have spare pilots that will be available to go away for a length of time. You will also have to consider performance requirements when choosing the model of 109 you wish to employ as the older ones are a little short of breath, particularly on one engine.
