Hello and thanks for the donation
if the shop said the ball joint needs replaced, this is most likely the cause of the tire wear in the first place. You can check the ball joint by jacking up that wheel and trying to wiggle the wheel. If it has freeplay in it than the balljoint is bad. You should be able to get the ball joint replaced at or below $200, including labor and parts.
