Keep it on Squarespace. Tidy it up if you must/want. But Squarespace for a year is a lot less than the time you'll spend building (and then looking after/changing/whatever) it, even if you end up hosting it for pennies afterwards.

Assuming stone mason types appreciate master-y of an art form you could begin your adventure on sdf dot org's faq page. Having registered the name and put together the webhost stack on a NetBSD platform you are good to go with the html/css/js framework. It is something I want to do but never get around to doing myself. The end state looks like a website you see on your local desk Mac and then you simply synchronize your file system assets with your webhost's file system. Lots to learn along the way. You could go deep and digress to reading the IETF RFCs for what is coming around the corner to the future!

If you must keep things bare bone, try hosting the site on GitHub Pages https://pages.github.com/.

There's nothing simpler than doing nothing...if it ain't broke...
