Perhaps you could look for a retired teacher or one who has just had a baby and wants more flexibility. Not sure where you would find such a person.
This was my thought, or: teachers fresh out of college who don't yet have a full-time teaching position. Or teachers still in college. I earned my Masters in Teaching through WGU, which is online, and would've taken a job like this when I was a student. At the salary you're considering, you would have to find someone who is being financially supported in some other way (like by their spouse), which will definitely make it harder.
