How can I get more baby-sitting jobs?

My aunt bought me shirts, hats, pens, signs for the yard, notepads, cards, signs for your car and everything. All saying "Bri's babysitting!" but now they are in the study collecting dust. Where can I post/hang them so I can get business? Any good stores? I just don't want bad jobs (like the parent forgets to come back, probably won't happen but you never know.) but any job will do! I really just wanna put them on buisness boards so people can see them.
