You simply go over to clickbank.com and find some products that you want to promote. Signing up for a clickbank account is free, and you can make a lot of money by promoting clickbank products online. These products are not going to sell themselves, and you are going to have to advertise these products. The costs of advertising online can be astronomical, but you can advertise for 30 days for only $9.95 using eBay classified ads.
Each product that you promote via eBay classified ads is going to make you between $60-$100 in profit. This means that if you can set up just 50 classified ads on eBay, then you will be making anywhere between $3,000-$5,000 per month all from home while staying at home with your children.
You can read more about this book for moms to work at home, which focuses on how to use eBay classified ads to my a good income from home.
