There is a business called "My Pet Carnivore" that sells balanced, ground meats in 1 and 2 pound packages for very reasonable prices. All of their meats, unless otherwise specified are ground with muscle meat, bone and organ meat so they are complete. You would have to check to be sure but I do believe that they deliver to your area once a month. If you meet them at a delivery point, then the "shipping" cost is only $10. They have a fine ground option for several different types of meat if your pup doesn't like to chew up whole bones.
Eggs are also a good source of calcium - a whole, uncooked egg including the shell.
