Pattern Altitude
So the $200-$300 is no longer a consideration?
Realistically, I don't think it can be. But negotiating 101, start with an unreasonable expectation and walk it back from there... Now the question is, if we're going with a larger aircraft, are we better off with a large cabin class twin piston or a single turboprop? Hourly operating costs are roughly the same for longer flights, shorter flights favor the pistons by some margin. Acquisition costs (again, other people's money) are significantly higher with a turboprop but so is the wow factor for the customer. How much is that worth? There are pressurized Navajos and Mojaves out there in the mid-200s with low time engines. Put in $15k worth of interior upgrades and it'll be as nice as any TBM or PC12.
Also, are you sure you want to subject your golfers to an unpressurized aircraft?
That's also a thought. I don't think short haul flights wouldn't be too much of an issue. For instance Prairie Dunes in Hutchinson KS, incredible course but it's in BFE, same with Dakota Dunes north of Sioux City. An unpressurized piston at 8k would be comfortable if a little bumpy in the afternoon. But a flight to Chicago or Dallas would be much more comfortable in the mid-teens and I wouldn't think dudes paying a premium for a golf junket would want to shove a cannula up their noses. But as I mentioned, there are some reasonably priced pressurized pistons on the market.
Now, I say this all with the massive caveat of not ever having purchased an aircraft and not having dealt with the management that goes into a Part 135 op. I am friends with a guy who runs a 135 operation out of KMKC, I could pick his brain I suppose... This is all an ambitious brainstorm from my buddy, I told him I'd look into what it would take. So far, a lot. lol...
