What age player? You might want to check ebay. Great deals on batting cages or netting that can be used to do what you are referring to. The age of the player would dictate how far. To be honest I would not invest in netting but would use something soft such as foam to keep the ball from coming back and just use a softer ball that is made by ATEC. You can also use tees inside to do swinging and you could use small golfball wiffle balls. If you use netting, you could just hang some to keep it from hitting the wall and not use a full cage net. Again, ebay would be the answer.
