How Much is a YT Channel Worth?

How can we make the numbers work for the following:

  • I have a youtube channel where I make videos once per week
  • youtube shares half of the ad revenue with me
  • every video I advertise my presence on an alternative site where there's no ads, and more videos
  • the alternative site has the same third of my videos as youtube as well as another two thirds of premium content for those who pay
  • in addition to the additional videos, the alternative site has novel interfaces, blah blah

How can you make the pricing of the withheld premium content exceed the value of that same content published to YT with a half-half ad profit share?
