Yes, try Netjets and/or Flexjet. If you insist on your own aircraft, which I understand, what about a Citation Sovereign/Sovereign+ ? If you want to have some more space, a Falcon 2000EX EASy would be a nice choice, too. The purchase price is quite okay at the moment (20 year old plane, 10k+ hours for up to 10mio USD is not a bad deal. The maintenance is more expensive than what you were used to from your XLS. What is your budget?
