Pace...please don't perpetuate the myth that single pilot ops are dangerous and expensive...
I was named on 5 Citations at one time as a Single Pilot Captain...and everyone's insurance dropped...which is one of the reasons they wanted me on board...insurance rates are dependent on the pilot background, ratings, and experience.
As far as accident rates...those operating under the exemption/waiver...not the single pilot type enjoy about the lowest accident rate in the industry...the only guys crashing jets single pilot are the biz owners....not the pros.
