If I may add a note of caution, technology has allowed scam artists to automate their craft in devious ways, it appears the term Work at Home is the favorite bait of these operators, for example searching for that phrase here will bring up Sponsored Advertisements for Work at Home for Google schemes, one titles "Top Work From Home Programs For 2010" describing part time work paying $6397/mo, oddly showing a photo of a Google paycheck for $32,290. People may have lost millions on this one ongoing deception $50 - $79 at a time.

There are legit jobs out there, I won’t bother to list them here, they are greatly outnumbered by the number of deceptive offers by anonymous operators from around the world, you may be best off only listening to friend’s recommendations.

It seems safer to pursue online freelance contractor work or to start a home based business.

People with unique technical and creative skills can offer their services as a freelance contractor through one of the job bid sites including elance.com, allfreelance.com, getafreelancer.com and project4hire.com

There are no sure deal online businesses, many people never find their way, the authors of get rich quick courses may be some of the more successful ones out there.
Some people create blogs that over time may develop a following that provides on site advertising income, if you can get on TV like that celebrity gossip perez hilton, your blog could earn a million a year, many try affiliate marketing, helping sell everything under the sun for a commission, there are signs that Google wants to sweep away affiliates, like annoying street hustlers. One site specializing in easy to create digital products, Clickbank has some 100,000 affiliates promoting nearly 10,000 products, due to no real production or shipping costs affiliates earn a typical 50% commission.

Those with no special skills can write short 500 word articles that are the main attraction of countless web sites that need to constantly renew their to maintain their ranking on search engine, their essential source of traffic. A quality article may typically earn $5.
