Take a Hawker!
Nuficek,
At the end of the day, it will always be a compromise between your budget and your operational requirements.
In the long run the Hawker will deliver the most bang for your buck. It might be somewhat higher in your initial cost, but reasonable operational costs and being a very reliable airplane when it comes to maintenance will make up for it.
Performance seems to be geared towards your type of operation, the cabin size is nice and very comfortable for you passengers. Baggage space is not great but sufficient.
Should you some day decide for an upgrade, the resale value will make up for the initial cost.
