Developmental Editor for Relationship Workbook (Amazon KDP)

I'm looking for an experienced developmental editor to review my nonfiction relationship workbook before I publish it on Amazon KDP. This is not a novel. it's a guided workbook with 15 conversations designed to help couples strengthen their marriage before and after "I Do. I'm looking for someone who can improve the flow, structure, reader engagement, and overall quality of the workbook, not just grammar. Experience editing nonfiction books, workbooks, journals, or relationship/self-help books is preferred. Please include examples of books you've edited, your editing process, and why you'd be a good fit for this project. I welcome honest, constructive feedback and want to create the best possible workbook.
