At that rate and with club seating you are probably only looking at 2 options, Bonanza, or Saratoga/Lance. Josh has a great suggestion but not sure your budget will even stretch that far!
I have a couple of questions:
Are the consultants willing to fly in a single? Many are not.
How many hours are you looking at doing per year?
If it were me, I'd be looking at a Beech Duke (mainly because I like them), if money was no object then it would be a turbine Duke!
