I used to do medical transcription from my home. I had some medical courses, such as EMT/Paramedic... I just used that experience to build my business on. You don't have to have any courses. Decide how you want to do it and then start your own business. Make sure you have lots of books and dictionaries. You have all access to anything you can get from a class online right now FREE. Anyway, one thing I do want to point out that this is NOT an easy thing to do. You have to have a quiet area to work, you have to work a set amount of hours. You have to be able to understand a lot of foreign accents. If you aren't interested in doing it yourself, I always recommend www.mtdaily.com. They have lots of jobs posted there and sometimes even, no experience necessary, positions.
