Don't do a donation and a price tag, pick one. Your just being greedy. Plus no one knows if your content is even that high of quality you show 2 min clip of you just moving your mouse around and giving an overview. Plus your voice is kinda hashed and monotoned.
I've decided to make the first 200 slots free. Enter the coupon code free200.
Sry if I came off strong. I just meant there is plenty of free information out there if you do a little research. For the general public to see your "course" they prob already read through a bunch of information already.
I think you would be best off taking the $9 fee and just accepting donations until you get "accepted" then maybe add a small fee and drop the donation gig.
All recommendations, I understand you would like to get compensated for your time but in the long run building good feedback and a small following will be best for you.
