Something else I recommend is taking the free 7-lesson mini-course on general transcription offered by Janet Shaughnessy of Transcribe Anywhere. This will help you to understand if you're a good fit for a transcription career, what you can potentially earn, and also where to get started. Janet also has free legal transcription mini-course if you're more interested in going that route.
A word of caution: Remember that where very little is required, very little is offered. These jobs don’t pay much, and they are not going to provide a reference for your resume. It may take working at several different of these online jobs to pull in the income you want. And as always, know the signs of a work-at-home scam as you sort through the opportunities.
