I've written a childrens picture book and have got the 2020 writers and artists yearbook and have gone down the list of childrens publishers one by one, and gone to their website for submission guidelines and they're either not the right sort of publisher (don't publish the book that I am writing) closed for submissions or require me to have a literary agent. I'd rather keep as much royalties as possible and find out how to pitch my book to a publisher myself, so any links on how to do that and any names of publishers I can submit to without a literary agent would be great
