Can’t answer your Q, but maybe they should contact Louis Rossman & see if he can be their main go-to person for repairs on the Apple side. I’ms sure he will love what they’re doing & hopefully provide some sort of discount.
I take it they have a ‘lab’ where the kids come to learn and play? Maybe they could do a rent-to-own model for families who can’t afford the cost of a device upfront? I’m tryingt o think of ways they can expand , without having to play cat & mouse , in terms of constantly buying more and more tech for the kids to learn on VS the kids bringing their own devices.
