Good Day All

I am preparing to buy a Jet (2000-3000 NM Range) for my company. This will be our first, so I need some advice from the ones on the ground (the Pilots and Engineers).

If we put together our own team, we will pay well and have great benefits for our team.

Our Needs are:
1. Will have a 2 Jet Fleet. Buy now 1st Jet (2-3K NM Range / 8-9 Passenger) / 2nd Jet added in 1-2 yrs (5-6K NM Range / 10-14 Passenger)
2. flying over the Atlantic and Gulf / N&S America, Europe, possible Dubai
3. Flying 3-400 Hrs Per Year

Need Advice on:
1. Do we set up our own flight department or contract it out? Would like to have the very best Team and the same team all the time.

2. We will need personal security occasionally (not Afghan stuff). Is it possible to hire both Pilots that are former military and they operate as personal security when needed as well? This would eliminate carrying added bodies on the plane.

3. We want the biggest and best bang for the dollar when we buy both our jets. So for the 2-3K NM Jet, what planes have the best track record?

Thanks in advance. I know there are far more details that are needed, but we are new to this area and want to have the best team and best equipment for the dollar. Have a Blessed Day!!
