Ebook format

I am looking for an experienced freelancer to help me format an ebook. The desired format is PDF, and I do not have ready content - I will need help sourcing content. Regarding design, I am open to suggestions. The right candidate should have extensive knowledge in the field of book formatting and be willing to help me with the sourcing of content as well. If you think you are the right professional to help me with this project, please reach out.
