At the moment, its challenging for creators to generate income from Peertube. In theory, the avenue they have is through patreons and the like, but in practice, peertube doesn't yet have the volume of users to make that work. And as a result, it's going to be hard to use any kind of "premium/paid" tier service, simply because there won't be many takers.
In my mind, right now, if you're trying to attract creators, you're going to need to reduce as many barriers as you can for them to move over. That may mean co-existing accounts on bigtech platforms and on peertube, and in terms of helping with your running costs, voluntary donations are the best way of doing it for now, until peertube gets a larger volume of users.
Either way, we spun up our own peertube instance a few weeks ago too, so welcome to the vidiverse :)
