Where can you find a summer job if you are 14 years old in Cleveland Ohio?

While I admire your ambition, in MOST cases (and in most places) businesses cannot hire people as young as 12. Your best chances will be to look around for neighbors that may be looking for some part time help in matters such as weeding flowerbeds, babysitting, and the like. Looking for those jobs will not be easy, but it WILL be good practice for when you are older, and looking for a regular job. Good luck to you!
