Be careful with the exec jet options being discussed here. It's simply not realistic to assume you can just dump "stuff" in the cabin. For example the baggage bay on a 604 (from memory which has been pickled by excess grape juice) has a capacity of 500 Lbs.
The average 604 interior is for 8-10 people. Assume 10 of you 230Lb Gorillas and 500Lbs of cargo, you are still short of your 3000Lbs.
If you are seriously considering dumping "stuff" in the cabin, you need to be talking to TC to see what they will let you get away with.
It might be that you need something like a combi CRJ (if such a thing exists) and even then I'm not sure it will do 2000nm's.
Good luck.
