Q:“Will Magnify build and maintain our channel for us, and how much does this cost?”
Magnify.net is a platform. We think that you will do a far better job of creating and managing a service that meets your users' needs. Because we share in the effort, we also share in the revenue. We think a fee-based channel creation service isn't as much fun for either of us.
That said, if you get stuck you can always email support@magnify.net or use the "Need a hand?" link on the home page.
