I administer Moodle for a private college (~1500 clients) and find that it works very well; one free / open source package gives us web-enabled classes (of course I also spend a lot of time training and supporting the instructors to make this a success). What shortcomings have you found in Moodle and other FOSS offerings? Maybe improvements and support to one of those is a good business model. If you do start coding from the ground up, I recommend targeting private schools where you might find less bureaucracy/resistance.
