American Proofreader Needed Quickly

I have a document ready for basic proofreading and I want a native-level American eye on it. The task is straightforward: correct spelling, punctuation, grammar, and obvious word-choice slips without reshaping the voice or structure. I’ll supply the file as soon as we agree to proceed and will confirm the exact word count then—it’s within a typical single-session workload. Please return the text marked-up in Track Changes (or Google Docs Suggest mode) plus a clean copy. Turnaround time and accuracy are my top priorities, so let me know how soon you can deliver and any similar work you’ve handled.
