Students working for Janitorial Services.

A lot of my friends in college have worked for a janitorial service. It's actually a great job for college students because they're dedicated to doing a good job, it's good pay, and it is convenient hours. I wonder if a lot of janitorial companies hire students. It could be because the service is located in a college town and students are the majority of people looking for jobs. http://www.patmarclean.us/services.html
