Hey a lot of people can make a lemonade stand, but these ideas are ones that require some skills.

1. Lawn Mowing, wait before you ignore this listen. If you tell your friend that you’ll give him (or her) $15 for mowing a yard and and you charge the owner of the yard $30 for mowing their yard.  Your friend makes $15 and you make $15 for setting up the lawn mowing appointment. Get three friends to do the same thing and your money starts adding up.  You can charge and pay different amounts but if you do it right you make money. The skill you need here is persuasion. 

Hey I found a great internet site called microbusinessforteens.com.
