Possibly, but I’m not very familiar with wordpress.

I imagined something like:

nextcloud.com/partners/

The idea is that I could pay someone to admin the same services that they provide to the public.

So like maybe lemmy.world and the other popular instances could offer a Lemmy instance, and maybe also offer: matrix, pixelfed, mastodon, etc etc.

There are decent options out there for mainstream services like email, web, etc. but maybe not for more niche services like lemmy.
