Jazzpianoskills.com has a free weekly podcast. If you wanna play jazz piano these are the skills you need to get there. It is great to have a PhD in jazz education to step you through the process. There are 4 years of weekly lessons you can access for free.
I have been teaching for 35 years. I am a lifetime paid member of this site. I am a big fan. The presentation is excellent. Having Dr Bob talk you through each lesson is highly motivating.
