It def makes sense for a one off thing. Though I was hoping I could help use or start a new provider for many folks here and get some sustainable number of clients to make it worth your time.

If I can get other people to sign up I would be willing to drop it to 2k sats, or less and even build a ui to purchase access to it
Nice! That could definitely get a lot of people interested. How would the resolver know if the user is a paying user, though?
Either a unique token per user. This is included in the sdns string for DNSCrypt
Or a user generated cert. Either choice works. And would be used for auth only and then dropped.
In fact now that I think about it more, the token could be a cashu token, so the payment and auth are the same process.
