Hey, I'm a professional transcriber & I can transcribe up to 3 hours of audio/video transcription day with timestamps. I did Australian, American & British transcriptions before & have proper & clear understanding of accents, culture & people. I also can easily transcribe Indian or Latin English transcription.
I went through your requirements & I did this kind of lectures, conferences & YouTube videos before. Like I said I can work up to 3 hours or more a day. I think the proper understanding of accents, culture and listening skills with a little bit of research is the key to quality transcription and I have those skills and I use them cool headed.
To brag about my past experiences, I worked with American, Canadian, Aussie people before. I worked as Customer Care Executive & Support Coordinator as US based & Aussie companies.
I'm fluent in English, always been good in presentations & making reports as I always loved to do researches. Like I said in my description, from a socioeconomic research to a critical SPSS internship report on a topic like Corporate Governance, I've done it all.
