Salary for User Support Manager

I am new to this discussion group so I am hoping I am posting this topic in the right category.

I am curious if the members of this discussion group have any information as to what salaries are out there for a user support manager that works in an educational setting specifically in k-12. I am one of those and I want to compare my salary vs national numbers and I am having a problem finding this data on the web. Any references to links are hard data would be great.

Thanks!
