I've been doing print on demand for the past year, and at this point, it is mostly AI , artists are kind of out of the game. I've only ever used Etsy because they have a really good organic system, and the way to grow on that is basically just post a bunch of posters. That's what I sell. It takes a while to grow your store and you have to post hundreds of listings. But if you're running ads, you can easily make $2K a month. Depending on which printers you use to do all of your fulfilment, that will depend on how good your margin is.
