Babysit, walk your neighbors dogs, lawn care.
How to earn money during the summer holidays?(I'm 15 btw).
You can walk peoples dogs who are elderly, help disabled people, cut grass, get a paper route in your area .
If you go to church and they have a nursery you could work in there every Sunday or whenever they need help...sometimes they also need nursery on Wednesdays and sometimes even other nights or days of the week. If only they pay their workers. I know at mine they pay us to work but a lot of churches just use volunteers.
