I have worked from home part-time as a freelance writer for nine years. I run my own business. If you want to avoid scams and bring in a decent income, that really is the way to go. The Small Business Administration website has some good information about getting started. Also visit www.wahm.com for some useful articles and boards about working from home.
Keep in mind that if you want to earn a decent amount of money, you may need childcare. I couldn't get sufficient work time otherwise. There's no way I could watch my kids and work simultaneously.
Good luck!
