Coaching Jobs in Ohio

My son is 14, 6'3", 185, is playing football (fall), basketball (winter) and track and field (spring). I would like a coach to work with him on his throwing in the shotput and discus. He has thrown 36'9" with 8lb shotput and 66'8 with discus with no form or formal training. He will be going to high school in the fall, and the shotput goes from 8 to 12 lbs. I have bought him shotputs ranging from 6 to 12 lbs. to practice on his own, but I am not a throwing coach. He also sprints, 100, 200 and needs work there are well We reside in Gahanna, OH.
