I did it, and I am as successful as I want to be. I am booked out until August of 2014...I don't make a killing but I do
make a bit of money here and there. I have a business in my home, and as I said, I stay busy. If you want to do it, make a business plan and stick to it; advertise, get the word out that you are reliable and do good work...and you'll have all the work you can handle. But...and yes, this is cautionary...don't go into it thinking you're going to make a mint, 'cause you probably won't...at least for awhile. Good luck!
