I need $1,740 by September so what do I do?

Long story short I need $1,740 before August 29 and I'm only 14. My school requires me to have a laptop and I also have other stuff I need. I just want to know how to get the money. I can't do physical labor so no mowing lawns or that stuff and no fast food place will hire me. And I don't get an allowance.
