You didn’t respond the second part: how much are you willing to pay for this? Anything less than $100k/year and I will guarantee you there is no serious provider who will care about being certified for it, and any who is willing to pay that much money surely will be better off by running their instance on their own.
I didn’t ask you to do any research. You said “I’d legitimately would pay for it.” and I asked one simple question: how much?.
This attitude right here is why the Fediverse is never going to become a viable alternative.
