The Sovereign is too expensive
Fair enough. Not being a Cessna salesman I wonder have you thought about leasing one? Or another airplane? Lease it for a year, that could give you an idea how much aviation really costs over here (your profile says your based in Canada, have you been here/seen the costs? - we operate a lot into Russia, Ukraine, Kasachstan, Aserbaidjan etc. and fees around the airplane are a MAJOR point on the balance sheet.) I have made the calculations for my company and have nailed everything BUT these things (wasn´t told where the jet would go mainly, so...)
Apologies if you do know these things already, just wanted to point them out...
