Although you can get into a jet for that, it will be range limited, need to employ crews (unless you get a 500SP), be ruinous to run at low altitudes and will be in the $2000-3000/hr range to operate. My suggestion would be to get a twin turboprop. There are many to chose from, but since I'm biased, one of the later Turbo Commanders are hard to beat.
If you buy an 840, 900, 980 or 1000 model with the Dash 10 engines, you have wetwing 474gal capacity, which will take you 2000nm non stop. That's longer legs than any other TP (except the Merlin). This is very useful when you need to bypass GA unfriendly countries in Asia and the Middle East. The Commander will be able to land on any surface, grass, dirt. It will also get into shorter fields than the competition. On top of that it will go 300kts all day long and fly at FL310 if you need it to. There's a reason Commanders are so popular on the used market - they do everything really well. And with the later models, all the spar strap mods were a thing of the past.
With a Dash 10 Commander you're looking at $800-1000/hr if you play it smart. A lot of bang for the buck. Load them up with people and gear and go the distance.
