I'd definitely recommend looking into Kip McGrath Education Centres. They have a very diverse tutoring staff and tutees in most of their centres. You'd be working from after schools clock off to about 8 in the evening on weekdays and mornings on weekends. Rooms are stocked with plenty of resources so you won't have to bring anything with you for your tutees. Kip uses 1 on 1 tutoring, as opposed to classroom tutoring. Most, if not all of their centres are conveniently located next to train stations. Good luck!
