If you are looking for a service provider for about anything, including sand blasting services, go to "google.local.com". The screen will prompt you to enter what service you are looking for and the area you are looking in. Viola, the search results will tell you of all the companies in the radius area you specified that perform the service you are looking for. I did it this morning and found a company that specializes in media blasting antique and restoration vehicles. They use baking soda, corn cobs, walnut shells, glass bead, sand, dry ice and a number of other media ideal for the item you are having blasted.
Good luck with finding a blaster in your area.
