Inexpensive shared hosting that uses flat file CMS

hi. Hoping for some help here. I'm a writer looking to move my domain name and set up a very simple, static index page, about page, contact page and blog site. Just about as simple as a personal site can be. I also absolutely hate wordpress with a white-hot intensity. All I need is a flat file CMS with templates that I can alter myself to achieve the look I want.

You wouldn't think I was asking for much that didn't exist in the late 90s, but I cannot seem to find anything that isn't overblown, sluggish and full of garbage I do not want nor need.

Budget is super small, but, again, I don't think I'm asking for much.

All suggestions really appreciated.
