Is there a quicker way to grind a 12 oz. (340.2g) bag of coffee beans?!

Question: I've been using a 2.5 oz.-capacity grinder (enough for a 12-cup), but doing small portions at a time is killing my lower back. Are there shops in the Van Nuys area (Los Angeles) that offers a better way to grind bags of coffee beans faster? I know it'll be much more expensive to buy larger capacity grinders, aside from being difficult to find anywhere. Got any ideas? Thanks!
