Ask HN: Best way to set up a website in 2018

Say you are a part of an association, or an organisation, or a small company which has no or very outdated online presence, and you have been tasked with fixing that. A pretty common situation.

Now, you like/work for/are otherwise compelled to help this entity. You want to make this happen and you can and also want to code. Like always, the budget is small (say <100-200€$£ one time plus 5-20€$£ per month, the cheaper the better (relatively) of course) but your time is ultimately free, even if you only have 1 to 4 hours per day for it. Deadline? Well, the faster you are the more street cred you get but end of summer is fine.

Regarding specifications for the site, you are told: "Articles, news, calendar, media. And other people must be able to edit them, too!".

How would _you_ do it? Or a better version of _you_?
