Just to showcase my business/field of work, not selling anything. Is Wix any good, or Squarespace?
Easy to do yourself - I'm not the techiest of people nor have masses of time to dedicate to it?
Or just pay someone?
Nearly every domain host will have a web builder that you can throw a basic site with static content together on. There will usually be a free / heavily discounted first year.
Wix or Squarespace should be spot-on for your needs.
Doing website content is a big part of my job, and I made my own company site and a personal blog in WordPress - but it's not the most intuitive and gets a bit niggly.
I'd say have a go with one of them first, as you might spend just as long briefing someone to do it for you as you'll take doing it yourself.
