Well, like I said, I’m also a new writer-let me see what I can do
Well, Amazon has a sort of self-publisher thing where you can publish your story as an e-book.
Or, you can Google some publishers, and email them about your story. I’m sure there are lots of websites that can help you in regards of how to write a proffesional email. (I’m haven’t done this part yet.)
Is your story completed? If you’ve typed it up, you might want to run through spellcheck (although you probably have). Also, you can get a proffesional editor to check for tiny mistakes and for advice on the plotline and characters. For now, I just have a really close friend who’s also an English teacher.
For page length, that depends on what kind of children’s book. Is it a picture book? Becuase they don’t have much pages. On the other hand, children novels like the Percy Jackson series by Rick Riordan or Warriors by Erin Hunter have about 350 pages each.
That’s all I can think of right now-I hope I helped in some way.
