I've got quite an unconventional answer to that. I haven't taught in ten years so I'm going to start by giving free one to one lessons to beginners and intermediates. I would like to have 5 hours of material for both levels. However, I do plan to get back into the classroom through this strategy, so any and all resources are welcome here. My hope is that all teachers can read this thread and get/contribute something useful. Cheers!
