I saw this on ABC News and it sounds like a great idea!  TaskRabbit is a like a job posting website within your own neighborhood.
TaskRabbit let's you post your services, offers an outlet for people looking for services to find you - and according to ABC News, people are making up to $5,000 per month in doing so!
The catch?  So far TaskRabbit is only available in San Francisco, Los Angeles, Orange County, Boston, New York City and Chicago (with more cities coming soon).
