I am a software developer, but not a website expert. I could spend the hours learning the basics, but am looking for someone to put together a “shell” of a site for me that I can then take and flesh out and learn RapidWeaver and Stacks 4 etc.
You could just start a site at a free board ; https://www.proboards.com/forum-directory
It has a lot of advantages, learning to use RW could come later with something simpler.
You realize you are asking a lot, without any further input?
You could just try playing with any free (donation ) theme, like this one as your main page. https://themeflood.com/preview/supporty/
or as the subpage to another from here.
There are many other theme developers.
