Consider to make short videos it is a best way for tutorials. Also, you can create a pdf , some kind of mini ebook course, it would also be helpful. What I mean is after whole course you can put all your writings and pictures from all your emails to one solid pdf to have everything in one place. If you want to put some videos, after emailing course you can upload all video files on some server on internet and leave us a download links in that pdf.
