Transcription work for a non-US resident - is $30/day an achievable target?

Hi everyone.

I had posted this very query on BeerMoney and was referred to this subreddit as an appropriate forum. I am a law graduate from India. Currently I am not employed full time and have a lot of free time at hand. I am not too keen on pursuing law as a full time career and am looking for alternatives. Recently I was given some transcription work by a research scholar pursuing his PhD. I transliterated and translated (to english) a few interviews.

I am getting paid ~$8 per audio hour, and a lot of the audio is in our native language which I need to translate to english. I would be a lot faster if the audio was in english since I have a typing speed of around 80 wpm.

This led me down the rabbit hole of transcribing online and I found a wide variety of services offering jobs. I searched here and found that a lot of people were not happy with the low pay.

Now, I am not a US citizen and our currency is relatively weak vis-a-vis the US dollar. From what I have understood, a company like TranscribeMe offers $15/audio hour, which for me would be a significant hike. If I was to transcribe 2 hours of audio files per day and earn about $30/day, it would be a very very comfortable amount for me. I have a few questions I wanted to ask in this regard -

1. What websites would you recommend? I have found services all across the spectrum by now, but I am looking for reviews from people who have actually worked on these platforms.
2. Is earning $30/day from websites such as TranscribeMe/Rev plausible?
3. How many hours of effort per day am I looking at to achieve that target? I am okay with putting in 6 to 8 hours of work per day.
4. Since I hold a law degree, does the per audio hour pay increase with experience? I could transcribe law lectures and other related material.
5. What websites would you recommend for someone who is a beginner but not so much a beginner? As in, I can understand the American and British accent very well. I have relatively okay grammar skills, which I plan on honing further.
6. What is the way forward? From what I can think of, work for websites such as Rev, TranscribeMe, etc. and then start approaching companies independently or on platforms such as UpWork.
7. Any other advice you would have for someone who is stepping into the industry?

Any help would be much appreciated.

Thank you.

PS: I just got a rejection email from Rev. I am quite surprised to be honest. I really thought I nailed the transcription. I can't seem to think where I might have gone wrong. I followed their guide to the T. I will try and apply again after 45 days.
