Last time I had a duck mounted it was about $80 bucks (90's). Gettin' old.
Not sure if she still does it, but Dorothea Munchow (spelling) in Metairie used to mount all my birds. Awesome work. Might be worth looking her up.
Kevin in pearl river does by far the best mounts especially on wood ducks; he charges $250 i think or maybe $275 but its well worth it. Before you get it mounted though you need to try and shoot a more mature bird; that one is a little scrawny. The better the bird the better the mount.
