I do medical transcription. I'm an indepedent contractor for a company in San Diego. They require you work at least two years in house somewhere before they'll hire you, and you have to have a year of training before you can get hired at a hospital or clinic.

Working from home is STRESSFUL! Sure, you don't have to commute and can work in your jammies, but the main office still expects a productive work day even though your cats are puking on the carpet and the kids are fighting and a house that needs cleaning is staring at you.

Not to mention that just about everyone thinks you don't have a "real job" because you work at home.
