my cousin, Mariah, is 10-years-old and her best friend, Tammi, is 11. They want to start a business going around to Tammis neighbors offering to do odd jobs (ex: dog walking, car washing, ect.). but Tammis mom said it was illegal. Is this true? Cuz Mariah is pretty upset about it.
      Answer1:No. -Just as LONG as its not an illegal business! (With kids these days- You never know!!!) :)
      Answer2:No. Cameron Johnson started his own business when he was 9 years old. He was a millionaire before he left high school. So no it is not illegal unless there is a deeper reason why your Aunt would say that.
      Answer3:Search: Business Empire MagazineIt wont let me put a direct link but they have a ton of information about ways to start or grow a business and should have answers to your questions.
