If we charge you only $9.99 - $19.99/month, we cannot use this money to finance free viewing for your viewers. Video streaming is data intensive and expensive. We'd have to charge you ca. $250/month to do this. If you agree to $250/month we can set your projects for free viewing.
Alternatively you can try streaming on EdCast/Vimeo for ca. $350 -$450/month
As you can see cost of streaming video and storage is not cheap.
