If you have never used private jets before, it is better that you check out the companies that offer you the service in your area.
A good website to charter a pivate jet is http://www.charteringprivatejets.com/
http://aircharterguide.com/ take a look here and if is a short distance I recomend you to rent an airtaxi, usually a Sirrus Airplane or for a long distance you might consider a Pilatus or a Piaggio Italian Airplane (very fast)
