Professional Editing Needed for Academic Manuscript

I am in need of a seasoned editor, preferably with a background in academia and a deep understanding of the humanities, to refine my 5,000-word document. This piece aims to deepen the understanding of participants' practices and transformations during certain ceremonies.

The editing required encompasses:

- Proofreading: Checking for grammar and spelling errors
- Content Editing: Ensuring coherence and clarity throughout the text

The ideal candidate for this urgent undertaking will have:

- Over 12 years of professional editing experience
- A strong history in both proofreading and content editing
- Previous exposure to similar academic content
- A keen understanding of style and tone consistency

If you are able to take on this task, please provide:

- Your estimated completion time
- Your proposed cost for the project

Additionally, I seek a skilled writer to assist in expanding my collection of 120 philosophical quotes into a full-length manuscript. Each short quotation, capturing my contemplations and life experiences, is currently between three to four lines in length and requires nuanced editing as well as development.
