You can contact Michael Rubin for lessons over Skype. I’ve been taking lessons with him for over a year learning the chromatic and diatonic simultaneously, and I highly recommend him! I’ve learned music theory from him as well! The lessons can be recorded, so you can download it and review at your leisure. I’ve posted the information below. Hope it helps!
