You can actually buy bulk calci-sand if you really want it. It's sold as an additive for chickens at any Fleet Farm or other feed store. Usually runs about $5-10 per 50lb bag. And if you have any concerns about impaction purchase a few flower pot bases and use them as feeding bowls. The Beardeds will quickly figure out what they are for and will eat straight out of them with the food never reaching the substrate.
BTW, since you haven't gotten your Bearded yet I'd recommend purchasing one that's at least 3-4 months old. And if you are going to only get one I definately suggest a male. They live much longer and tend to be far more personable then females.
