Anytime you are talking about pressurized aircraft - and
multi engine you are talking more than $200K.

According to your performce requirements a Kingar 90 would
fit the bill but I don't think you can find one for $200k.

I wouldn't rule out single engine airplanes, there are
many that could meet your mission for a lot less cost than
a twin.
