I am the developer of https://golfcourse.wiki https://golfcourse.wiki which I see as very conceptually similar to what you're trying to build. It's on App Engine, the front end is HTMX, my backend is Flask, and my DB is mongo. If you're in the SF area, I'd be happy to discuss the project with you, costs involved (pretty low), etc. I honestly had no idea what I was doing when I started it during the pandemic, but I now have about 2k unique users per month, and it seems to be holding itself together pretty well. My best metrics are the google search results which are going in a very positive direction.
