correction of spelling and grammar in my book

I am looking for a skilled proofreader to correct the spelling and grammar in my book. The book is written in English and has a word count of 5,000-10,000 words. I prefer the use of British English spelling and grammar standards.

Ideal Skills and Experience:
- Strong command of the English language
- Excellent proofreading and editing skills
- Familiarity with British English spelling and grammar standards
