What can someone do as a job at 13 to earn extra money?

I have a younger cousin who will be turning 14 by the end of the summer. My uncle-(her dad) does not pay her allowance believing in the strict doctrine that children need all of their necessities-(clothes,shelter,food,educat... and that's it. No allowance even for chores or good grades. My parents are not like that and I feel sorry for her. She is desperate to earn some side money in her free time-(which she has a lot of) but she is young and can neither work at a mainstream restaurant nor tutor. Any other suggestions of a job for someone her age? I really want to help her out but have ran out of ideas.

Jobs

There are many ways you can earn money. I babysit and I get paid very well. But I think you have to be 13-14 to start.

My Rates

1-2 kids ~ $5.00/hour
Each additional child ~ $1.25/hour

*When you are babysitting a baby under 10 months old, you should ask to be paid a bit more than your regular charge, since you must give more attention, change the baby, feed the baby, and put the baby to bed.

Another Idea is to have a bake sale/ lemonade stand. Me and my sisters baked all week, made poster signs and decided how much we should charge for each baking good. Any age is perfect for this job!

Another good job is to start a walking dogs for neighbours that have dogs. You can either put up posters around town, or hand out fliers to people you know that have dogs. I would charge 5 dollars per dog.

Another good job is to wash cars, or open a car wash business with friends for a few days, mow the lawn, shovel drive ways in the winter, and help people clean there house that might need help.

If are 14 years or older, you could also work at fast food restaurants, or grocery stores too.
