It would probably be pretty easy to create a tutorial that gets someone to set up a github account, introduces the basics of git/html/css/javascript, and ends up with the tutee having a Github Page that demonstrates what they've done exposed to the world on the internet. Include the DNS setup via cloudflare if they want to buy their own domain.
Are there not tutorials like that?
And then there would be next steps, using free tiers of online services to add a backend etc. There's quite a lot of places to go from there though. What would be best?
That's basically what we do with https://www.makeitwithcode.com, we take people through building things and teach them theory as they go along. Then we go through deploying something to Heroku etc as part of subsequent lessons, so by the end they've got a mixture of the theoretical stuff as well as the more practical "how do I make this be on the internet".
I think there's a few others which also follow the approach of each lesson essentially culminating in a new portfolio piece.
on the homepage bottom-right it says:
The course costs just $200. If, during the course, you feel you're not getting value for money, we'll give you a refund.
You'll get a lesson a week for 10 weeks. The lessons are text-format, combining a balance of challenges with instruction.
