Ah, bufala mozzarella and fresh tomatoes... and sauvignon blanc (unconventional, I admit, but still...)
Nah, no such thing as a used AW-139, not yet, certainly not 3-4 of them, and while initial indications are it's going to be a terrific aircraft (I hope so, I'm planning on flying it sooner or later), a small operator is probably not the one to sort out the inevitable bugs anyway. That's why I was aiming you at the N2 Dauphin and the 76C or C+, they're probably available and reasonably mature. I figured you had a time constraint as well as a budgetary one.
Also, remember, depending upon your geographical peculiarities, you probably only need "so much" helicopter. To get the wrong machine is not to optimize the operation. Like I said... I'd start by bracketing 10,000# by maybe 1500-2000# either side... anything smaller probably won't suit, anything bigger will probably cost too much one way or another.
