There's a business here, some kind of geocities for businesses

They don't need their own domain, it's all just subdomains or subpages like barber.businesshost.com or businesshost.com/barber

And nothing complicated, just an easy way to edit a single page, maybe change the colours and add a few images. Hell, drop any Markdown editor in there.

Specifically don't allow sub-pages, internal links, any kind of booking systems or webshops etc. Just a basic plain page with address, opening times, menu/prices if it's a place where that matters.

If they want anything more complex, they can go to Squarespace or something with all the bells and whistles.

You can host a service like this on a $5 VPS for a zillion companies, bill them $5/month and you'll be net-neutral on your first customer (- dev costs of course)
