Content transcription (text)

I am looking for a freelancer who can transcribe audio and video content into plain text format. The length of the content varies from less than 30 minutes to over an hour. Timestamps are required in the transcription and I also need speaker identification. The formatting requirements are plain text only, without any additional formatting. The ideal candidate should have experience in transcription and be proficient in English. Attention to detail and accurate transcription is crucial.
