Interested in becoming a pet sitter at 13

Hello, I did not know where to post this, if there is a better place or site, please inform me.

I am thirteen years old, and I have an interest in becoming a pet sitter. I'm comfortable with most animals and some of the grosser stuff, like cleaning up waste or feeding bugs to reptiles.

I know that at this age it's a tough thing to do, since I have a busy schedule with school and vacation during summer. However, animals are something that I'm passionate about and I would like to earn money...
