I make about $800/month selling place card templates and formatting at https://www.placecard.me/ https://www.placecard.me/. I started the project last year and made $3 in my first six months. But have seen pretty decent slow and steady growth since then. I've written extensively about the process on my website (http://www.coryzue.com/writing/ http://www.coryzue.com/writing/) and on indie hackers in case interesting to anyone.
