OP, Ste Hughes may have been harsh but fair, but he is right. This is a little bit below the usual business question we (the elderly) would like to have posted. Although, I do like your entrepreneurial spirit!
I would consider developing a plan to get all of your local schools involved, while asking the faculty to help by holding events at each school. They could be fundraising or whatever, but try to get other people selling these badges for you.
For instance, each school allows kids to sell these to their classmates for a percentage of your profits. They could be competing for a prize as well, like whoever sells the most gets a prize. The key here is to scale and allow others to do the grunt of the legwork (sales) while allowing you the time to oversee and manage a sales team.
Perhaps the schools could even use it solely for a fundraising event, while you get credit and respect (as well as an awesome milestone for a resume). The lesson you learn here would be invaluable at your age.
Start small with just your school and branch out and maybe eventually you could have a decent system to put forward towards a college education. Or IM education...
For all the haters out there:
