I'm writing for a foreign Azn KDP market. The niche I picked for my first three e-books is pretty much saturated by the looks of it. I get fewer and fewer sales every day, and that can't be good. I need money. Since I just cannot fathom romance, erotica and all that soapy shiz, I've decided to start cranking children's books. The thing is, Azn doesn't accept content from wikipedia, and I wanted to write about animals and educational stuff. Where can I get the info without being accused of plagiarism? Are there other themes that are good for children? Also, does anyone know where I could get decent free images for kids? I'm too broke to pay for 'em, so they'd have to have a commercial CC license (or something similar). Thank you so much!
