Verbatim Transcription of English Audio

I have an English-language recording that I need transcribed exactly as it is spoken—every word, pause, false start and filler included. The file has some background noise but the voices remain intelligible; accuracy is still crucial because I’m comparing the transcript against my own notes to confirm what was actually said.

Please deliver a clean, well-formatted text document (Word or Google Doc is fine) with speaker changes clearly marked and timestamps every minute so I can cross-reference quickly. Let me know your estimated turnaround time once you’ve heard a short sample, and feel free to flag any sections that are genuinely unintelligible.
