Build email list of elementary school teachers in the United States

I'm looking for an email list of elementary school teachers in the United States. I would like the list organized by state, within each state by school district and within each school district by school.

I would need the teachers' names, ideally separated first and last. If it is possible to include the teachers' jobs (first grade, etc) that would be great.

I would first hire you for a short amount of time. If the quality of your work is good, I would hire you for many more hours.

Thank you for your consideration.
