$77 a month is certainly a good start, especially for a digital project. Then again, from what I saw in the images you are one of the greatest map makers I have ever seen.
If I was allowed to use my money on "internet sites" then I would donate to your Patreon. My parents do think of books as "appropriate expenditures" so I will certainly buy it if you come out with a physical atlas or publish the manuscript.
If you are looking for a place to publish the manuscript, I would suggest getting into contact with the (only) true AH publisher, Sea Lion Press (https://www.sealionpress.co.uk). It was founded by several AH.com users and accepts submissions.
Show your parents this footnotes document, which is just for the spreadsheet component of my project (the factbook). It's 11 pages of marginalia and further readings/citations for just explaining and discussing concepts and terms used in the spreadsheet. There's obviously a stigma associated with the kind of work I'm trying to accomplish here, but I don't see the message(s) I'm trying to get across nor the content I'm putting out there too different from what educators on YouTube are doing these days.
