Amazon eBook Manuscript Formatting

I’m preparing my fiction manuscript for Kindle Direct Publishing and need it transformed from its current DOCX file into a clean, fully-compliant Amazon eBook. The book already reads well; what I’m missing is professional formatting. Here’s what I need you to do: • Apply consistent chapter headings so each section appears in the Kindle navigation and a clickable table of contents generates correctly. • Use standard indented paragraphs throughout—no block style, no extra line breaks. • Build or adjust all front- and back-matter (title page, copyright, acknowledgements, about the author). • Embed basic metadata and ensure the file passes Amazon’s validation tools. • Deliver both an upload-ready EPUB (or KPF) and a cleaned-up DOCX for my records. No custom fonts are required; I just want the layout to look natural across devices, without strange spacing or orphan lines. I’ll preview the file with Kindle Previewer, so everything must reflow smoothly. If you’ve formatted fiction titles for KDP before, tell me briefly which ones and your usual turnaround. I’ll be quick with feedback and release approval as soon as the file uploads without warnings.
