I have checked out a lot of those work at home promotions and have found that all of them are scams. If they offer a large amount of money, beware. Some want you to pay $49.99 to receive their information first. I did this once, and found that their "booklet" was full of further scams.
Contacting doctors offices' and transcribing their work is a lot harder than one would think. AND, the pay is NOT that good. The only thing close to working at home and making any money is daycare, but you have to like kids, deal with lousy parents, and expect not to be paid very much. But hey! That's the exchange for being home with your child. Good luck. If you find something, let us all know.
