I would also consider what others are saying as a very viable option. You could work IT part time and instruct when you want and do fairly well as you progress through the ranks and gain some experience.

Depending on what you are into and the experience you begin to gain you can really have a ton of fun out there. In my time as a CFI I was fortunate to have some tailwheel experience which led me into aerobatic instruction in most aerobatic planes out there. My love for older airplanes scored me quite a few flight reviews in stearmans, wacos and travelair biplanes as well as quite a few others. After I acquired more multi time I ran into a guy who I did some part 91 work (non scheduled, personal use) for him in his cessna 414 twin.

Moral of the story..you can have one hell of a time flying as a CFI and doing part 91 work and some of the guys who I envy most have done just that, everything from tundra in alaska in a beaver to twin otters on floats inthe caribbean and then the occasional citation to the park city. A lot of fun out there to be had and most of it is not in the airlines.
