Then what you really need to do is sit down, and talk with an experienced pilot about your flying skills. A jet is an investment, not something you want to just jump into. You really need to start properly, buy a trainer and really learn to fly. Then move to a faster more aerobatic low wing airplane. If you really have the desire and drive to do this properly, you can probably take the needed steps up to a jet within a year. Starting with a jet, while I suppose it is possible, is not something I would recommend. The potential for loss of aircraft, as well as property in inexperienced hands is fairly high. These are true fire breathing turbine engines. While the reliability and ease of operation with turbines has become incredibly simple there is still much room for operator error, particularily in the flying aspect.
If you were to start with a jet (again, I don't recommend this) Then something like an AV8R or a Facet would be the way to do it. These aircraft fly nearly like a trainer. However, takeoff and landing speeds are higher and potential flight speeds are higher.

The best thing you can do IMO is to start off properly, if you want to get into turbines, you're going to spend at least $4000 to get a jet in the air right from scratch, for myself, I would want to have confidence in my abilities with that investment and know that I could fly well first.

Just my 2 cents.
