Also check out craigslist. You can see if anybody has posted a "work" ad, or you can post your own wanted ad.
I'm assuming you're a woman living alone, so this might not work for you. But my dad does a lot of work with the homeless, and whenever he needs to hire somebody to do light manual labor, he asks them first, because he knows how eager most are for good work. In his case since he's involved with a food kitchen, he knows exactly who to ask, who is responsible and hard-working. He says that if he was in a new place, though, he'd ask the manager of a shelter or food kitchen, because they're familiar with the people and who would be a good choice.
However, if you'd be alone in the house and don't want a non-professional alone there with you, then both of these ideas may not work well.
