Are you looking for something on-line or a school near you?
There are a lot of scam schools out there -- especially the distance learning ones. You pay up the wazoo to take their courses and find yourself unable to get a job when you get your "certificate" because you have not gotten any real benefit from what you have done through their coursework.
In my opinion, most people want to get into that line of work because they think that they can make a lot of money working from home in their PJs while their children play happily at their feet.
The fact is, the business has changed radically in the last 3-5 years with more work being completed by means of EMR and off-shoring (India, Pakistan, etc, etc).
