I'm planning a new project and looking for children's book writers for hire (https://inklinkpublishing.com/childrens-book-writing), but I'm unsure where to start. Who has actually hired them, what was your experience like, where did you find trustworthy writers, when did the collaboration work best, why do some projects fail, and how do you judge quality before hiring? I'd really appreciate honest advice or real experiences from the community.
