On line course , need some advice

Hello ,

Need some advice and suggestions

I am planning an online course on tatting for beginners; I've been tatting on and off for over 20 years, I taught myself from books , but tatting was not known in my country , people just started to know about it mainly from instagram. I already filmed over 30 videos totals over 2 hours , what price do you think will be good knowing that it is usually 45 to 50 USD for an hour or hour and half for other common crafts here .
