Doesn’t something like Wix take care of all of this?

Yes. It’s also idiot-proof enough that I sent a tech illiterate estate agent friend there with instructions to ask ChatGPT if he had any questions. He was up and running, with property listings, three days later.

Honestly, this is a solved problem - the actual problem, if you talk to folks who maintain only a FB page, is that they don’t want to pay.
