I'm not sure if your school does this, but some have this site called E*Recruiting through
Experience. It's basically a place where employers post jobs and internships and students apply for them via that site or the contact info the employer provides. Sort of like monster.com or careerbuilder.com. It even has a search where you can narrow it down by field, unpaid/paid, city/state, etc. You should look to see if your schools has it. Even if it doesn't I think you can still register and search the site for internships around your area. I have recently applied for unpaid interships and am waiting for responses.
