Children's Book Illustrator

I'm a primary school teacher from the UK writing a children's picture book. It's a dark and slightly scary bedtime story based on ghostly things my grandparents used to tell me about their house. The story is around 1000 words and I imagine will need around 14 pages of work as well as a front and back cover. I'm completely new to this so happy to answer any questions should you want to get in touch. Looking forward to sharing the story with you!
