Not sure how things are where OP is located, but some parents may not be able to afford something like this depending on their income.

If this works well integrated with school activity maybe it could be payable through that?

The OP is in Australia like me and while there are lot of parents that can’t afford to pay, there are lots of that could. The key here is to build your business around the customers that can pay, not those that happen to use it.

One other idea might to try and partner with companies that are trying to lock in young people. The obvious one is banks which are always trying to target this age demographics. You could offer, for example, premium notes to those students that had an account with the sponsoring bank.
