How to get $200 faster for a camera?

I'm getting the Nikon D3100 & I've only gotten halfway. I can't get a job yet because I'm too young rn & I don't look old enough. I'm only 13 years old. Any suggestions how I can get money fast?

You can't get a "real" job, but if you're determined enough you can make money mowing lawns, painting fences, walking dogs, babysitting, etc.
Ask for money for birthday and christmas.
Beg relatives.

When my daughter was 13 she was invited to stay for a month with her cousin in California (we're in the UK). We told her that we would pay the air fare but she had to get the spending money herself.
She went round all the neighbours - washed cars, mowed lawns, took dogs for walks, cleaned the house, ran errands, baby sitting. She asked all friends and relatives for money for birthday and christmas and she saved her pocket money. She did that for a year.

20 years later she still talks about that holiday as the best of her life.
