Most people just do a jet timeshare, doing it that way is much more cost effective.
I personally like flexjet

I would settle for a turboprop. Pilatus PC-12NG would be my choice.
There is also Set Jet which is more a charter service. Both are expensive, but I suspect as more of these alternative flight companies startup, prices will come down, especially with more pre-owned jets becoming available.
