Looking for an internship in Waukesha

Hello,

My name is Katia, and I am an 18-year old student from Germany. I'll come to Waukesha this summer for three weeks and I wanted to ask if it's possible to get an internship in your city. I know that I'm not aloud to work and I won't get any salary, but I really just want to gain some experience and improve my english. It would be great if someone could tell me where I could apply for a two or three week internship I'm interested in quite everything:) If it helps you, I speak german, french and english fluently.
Thanks
