Im interested in picking up transcribing audio as a small side job for some extra money, since I believe I will be good at it. I'm a fast typer, have excellent grammar and spelling, and a good knowledge of medical terminology.

I'm about to give birth any day now so I won't be picking it up immediately, maybe in a few months when I go back to my job. I'm also only a seasonal employee so it would be a good part time job to focus on when I'm laid off.

I just feel like I don't know where to start. I've located a couple of legit sites where transcribing jobs are posted, but I still have a lot of questions. What software do you use to transcribe? Word?
Any resources I can be taking advantage of to make sure I'm prepared? Most jobs I've seen will reject your work and pay if it's not up to their standards.
Is there a certain format you should use when transcribing?

If anyone can point me in the right direction, that would be awesome!
