How can I let people know I can babysit? -

Also, will people hire me? I m 12, almost 13.

The best way is word of mouth. If that s not reaching far enough, use local ads - classifieds in the local paper, cards in your local newsagent etc.You can also do PPC advertising if you make sure you set it up for local searches only. Most PPC sellers offer an introductory deal of a free $50 worth of advertising. That should be more than enough for you!
