oDesk.com

oDesk  is the marketplace for online workteams with the best business model for both buyers and providers.  Buyers receive guaranteed work (every hour billed is an hour worked) and providers receive guaranteed payment (every hour worked is an hour paid).  This approach makes remote work relationships as reliable and open as working in the same physical office.  Hiring managers can search the oDesk network and choose from among thousands of tested, top-rated  professionals from more than 100 countries.  oDesk allows managers to visually track and verify all work performed, through its web-based collaboration tools.
