Depending on where you are located at try a home design shop. Where I am at here in Colorado good big game heads will bring a premium price for those who do not want to go out and shoot one themselves.
I am from Southern Maryland. I have alot of Deer mounts, elk, zebra, gazelle, bear, kudu, leopard, baboon, etc. I havent put a price on anything yet, because Im just trying to figure out my options first.
A local auction house has a monthly sportsman's auction here in upstate New York (near Saratoga Springs) taxidermy brings good money. I've seen mounted bass sell for $300. I have no idea why. Dear heads go for $150 and up depending on the rack. African game sells for $300-$3000 depending on what it is and how good the mount is. If you google "Talk of the Town Auction" you can find them. I bet similar events in urban areas would bring top dollar.
You could also try contacting Gander Mountain or Cabelas - if they are opening a new store they might e very interested in acquiring some mounts. Good luck! Please report back and Let us know how you make out.
Then big stores like Cabelas and Basspro are good ideas but I doubt they will give the good money like the auctions do. Many guys will donate thier mounts for dispaly till they want them back, no money needed for the store.
Like Critter said some of the palces around here close to Aspen would give some really good prices just so they could display them and brag or show off. Being rich up there has certain requirements.
I have no desire to own anything that I did not hunt myself, or someone else in my family.
When placing a trail camera don't just look for a well used trail. What you want to do is look for a freshly used trail off by itself that goes from a north facing ridge, thick forest, brushy knob or some other similar bedding area to a food source. Don't forget water sources. Especially in the summer months the deer need water so look for a good trail going down too a creek surrounded by thick cover and place the camera 100 yards up from the water source.
Scent control is very important...
