Golf Swing Trainer Beginning

He hits hard grounders most of the time but i’d like him to hit liners and possibly a homer or 2. any suggestions for his stance, swing or anything else? He swing level and seems to turn his hips well. btw i’m a very supportive Dad and could care less if he goes 0 for 10. just looking to help him out.
