Proofreader for Marketing Book

Looking for a proofreader for my third marketing book. We have already done developmental edits so we just need the final proofread of 31,073 words.

About 8k words are already cleaned up podcast transcripts.

Please illustrate you have experience with business or marketing book proofreading and quote on the 31,073 words by the word or per thousand words.

We are a content marketing agency that has other work.
