Hi what a great idea you have! I recommend you find a local club in you area and take the boys out there and introduce yourself. Talk to the instructors and see first hand what you are getting yourself into! And if your real lucky maybe Even get a buddy box flight on the club trainer.
I did a quick search and found this club in Orem UT.
