Transcription proofreading

I need help with proofreading my transcription project. It is an audio or video file that lasts more than 1 hour and is in English, so no translation is required. I do not need any time-coding or specific formatting for the transcription. I am looking for someone who can help me carefully review the transcription and make sure that everything appears correctly. So if you have experience in transcription proofreading, please get in touch. I'm looking forward to hearing from you. Thank you!
