List of contacts at K-12 educational institutions in the United States

I require a list of contacts at all K-12 educational institutions in the United States. This list should include the following columns in some sort of spreadsheet-style list: State, City, Institution Name, Contact First Name, Contact Last Name, Contact Role, Contact Email Address. The institutions included in this list should include private schools, public schools, and homeschooling organizations. The roles on which I am focused are principals, technology teachers, language arts teachers, science teachers, and math teachers.

The list will be used as a contact list for a Kickstarter campaign to be launched soon for an educational video game.
