Copyedit Kids' Education Textbook

I need a skilled copyeditor to review and refine a children's textbook designed for early childhood learners (ages 4-7). The primary focus is on grammar and spelling corrections to ensure the content is polished and error-free. Additionally, I’d like the text formatted to maintain consistent headings and layout throughout the book, enhancing its overall presentation. The textbook should retain a professional yet engaging tone for young kids while strictly adhering to accuracy in language.
