I would try now, before the season is in full swing, try to find a college basketball player who is interested in “tutoring”?
Obvs not at a D1 school where they’re getting $$$ and have an insanely intense schedule. If you’re in DC, a Catholic U player maybe… the team runs a camp every summer and many of them work at it, so have experience with kids.
Not sure where to start but try the coach or athletic director who I assume are Google-able?
