As Dzug states, the vast majority of 'work from home' offers are scams.
However I supervise the delivery of Yellow Pages, working for a firm called Deya. I know that they're a genuine and responsible firm. They sometimes need 'route checkers', who work from home (checking up that my team have done their jobs correctly!).
I don't know whether they're currently taking on staff but it might be worth an enquiry. Details are here:
