NEED A PROOFREADER WITH EXPERTISE IN CHECKING GRAMMAR AND SPELLING CORRECTIONS

I am looking for an experienced and highly skilled proofreader for my project. I will be needing someone to proofread a book written in English, with a special emphasis on checking grammar and spelling corrections. The proofreader will have to be detail-oriented and able to accurately identify mistakes, so that they can be properly corrected. However, I am only looking for someone to check grammar and spelling; no suggestive editing or rewriting of content is required. The proofreader must have excellent English skills and an advanced level of understanding of grammar and punctuation to ensure a professional and accurate result.
