looking for help

Hi. Long story short: I found a pair of antlers from a buck that my father shot a long time ago, and didn't have time to get them mounted before he died 15 years ago. I was with him on the trip so I wanted to put the antlers on a plaque, but have absolutely no idea where to go for this service. I live in the Tempe area in Phoenix, and i would like advice on a shop to go to or something to get this done inexpensively.
