High school and elementary school buildings

i know that things do change from state to state but i really want to get involved with doing high schools and middle schools. i seems like all these new schools have a tremendous ammount of glass and someone has to clean it. i was wondering if any of you have done work for school and what is generally a good starting point in who to contact to get the work.

thanks steve

I have given a proposal to do schools before but they often say they have a janitorial staff for that. I went to the administration building for our school system to check on submitting a bid so that would be my suggestion as a first stop.

I do a private middle/ high school. It was a ref from a resi customer.
