Depends on how old you are! If you are old enough to get a job, literally apply everywhere. Don't just apply online but go to your local mall and go into every single shop, ask to speak to the manager and give them a copy of your CV. That'll help you in the long term.
For now, clear out your closet and sell anything you no longer use/need that is in good condition on eBay or something similar. Not just clothes, but if you have a phone/camera/iPod that you no longer use, you can make money pretty fast.
Also, if you do cheer already, see if your gym needs somebody to clean it. At my club, a couple of girls clean the gym once a week to pay their term fees. Just ask - you never know!
