Granite (http://tanbrown.org) sand (http://maplered.com) blasting

So does anyone have the number of someone who can sand (http://maplered.com) blast me a sign for the outside of my building . sign dimensions are 118" long x about 31" wide.

I want it done in black absolute or something similar, and (http://maplered.com) i will supply the Material (http://g654.org) .
Also if any one knows someone with a water jet, id like to have individual letters cut out also.

thank you very much.
