Collaborative Book Development

I'm looking for a skilled writer who can help me develop my partially written book about a deep relationship. The book currently consists of text conversations with context in between.

Ideal skills and experience:
- Strong narrative development
- Experience with dialogue and text-based formats
- Ability to weave context seamlessly
- Sensitive to emotional depth and relationship dynamics
What I have written is very raw and needs a lot of work... I'd like to finish writing it as I have been then work with somebody to polish it.
I'm open to suggestions and collaboration, as there's no time limit on this project.
