How to earn $700.00 by May?

I need to earn $700.00 by May 2011. I want to go to Washington, D.C. I live in Plymouth, IL. I cannot do much because of my small town. I do not have much to spend on supplies. (I do not want to ask my parents for ANY money) There is no kids to babysit, I live on a highway, I have nothing to sell, and I want to make this money fast. Put only good suggestion only. I need ideas, please help!
