Go to the flying field just as soon as you can, and spectate. Start encouraging your students to do the same. This hobby is infectious, and seeing it first hand almost always instills a strong desire to try it out. The Avistar will make a great trainer. There is a good argument for several other airplanes that might be "better" trainers, but young people have great "eye hand" skills, and are fast learners, particularly if you can get a flight simulator for them to practice on. Hooking up with a local club, or a mentor, will still be the best resource you can have. Beginning pilots can be instructed with the use of a buddy box, which allows the instructor to intervene if the student gets in trouble. Find out when the local club has their meetings, and attend one. Introduce yourself, and explain your needs for help. Even though you don't have flyable airplanes, and right now isn't the best flying weather, it's not too soon to start absorbing this hobby. Good luck.
