I was going to get some 2x4's to hold up a net to pitch into. How much would a 10x8 net cost?

Or however big you think that the net should be.I was going to get some 2x4's to hold up a net to pitch into. How much would a 10x8 net cost?
2x4's are generally 8 feet long. So if you go with 8x8 and your'e just thinking a frame for the net, then you need 4 of them. They're about 3 bucks apiece for stud grade (the lowest quality which is all you need). So that's 12 bucks. Plus 5 bucks for fasteners and braces. I have no idea how much it would cost or where you would get netting strong enough.
