Plans are to pair students up with mentors/teachers for one 30mins slots per week for free. We're hoping to extend it to 1 x 60mins or 2 x 30mins slots. We like to make enough to pay the bills and help students learn to write quality code.
I think what you're implying is that students could pay for extra lessons per week? You might want to work on making this explicit, it's really hard to tell what you're getting at here (I'm still not entirely sure). And to my original question: would the tutors get paid a portion of the additional time? Just really confused about what exactly the situation is you're presenting. I think you'll have a hard time rounding up mentors if you're unable to clearly explain it.
