I would strongly advise against doing 3 hour trips with 7 pax in a light jet (Citation Ultra, Phenom 300 or similar) on a regular basis. It really is not pleasant. And right on the limit of what they can do.
The minimum should be a mid size, and it needs to be long enough to be comfortable with more than 6 pax.
Better yet: I guess a Falcon 2000 Classic can be had for 5 or 6 million these days? Haven't checked, though.
