You're 15 so chances are you won't qualify for this but try and look for internships. They look a shitload better on a resume than any summer job you can get. As for easy jobs to get that'll make you some money for the summer? Listen to Baby Tea (a few posts up), his advice is sound. You can also look into working for camps and childcare services if you like kids enough. If worst comes to worst and you can't find work, volunteer somewhere. Even if you aren't making money you're not sitting at home bored and whoever you're working for will give you a killer recommendation. Volunteer work goes a decent way on a resume for future jobs.
I did none of this as a teenager... I had a bunch of shitty jobs.
