That said, I roughly assumed a private tutor cost of $50/hour, 5 hours a week, for 36 weeks per year. That alone would come out to $9000, hence the 'small group' suggestion- if each tutor is working with on average 3 students at once, it's a bit more tractable.
I'm not sure what assumption you think I'm making about current educator hours- the proposal is for a radically different usage.
