You may want to visit block times for your 700 mile mission. I doubt a jet will save more than 15 to 20 minutes on this. Maybe the boss's time is worth that much, but you may want to look hard at that. You have the perfect airplane for the mission, unless leg lengths are going to grow past 1,000 miles or you really need more room, you may be making a career limiting move by not putting the brakes on this one.
