You wouldn't save much, if anything, reloading 9mm yourself over what you can buy it for if you shop around a bit. Hence a commercial reloading place can't do it much cheaper either.
When I started reloading 9mm it's because I couldn't get it, not because it was cheaper. Now that it's available at reasonable prices again it simply isn't worth my time to reload it.
45 Colt now is a whole different story!
