I have 2 hunting partners who had full bear mounts done, both mounts were with bear standing up, on back legs only. Both look awesome to me. One was a 425lb bear taken in 2010, the other was a 465lb bear taken in 2015.
I baited for both, and had the "pleasure" of tracking down both of these bears, after the shot, after dark. Both were taken in Nicolet Nat'l Forest near Eagle River.
The 425lb bear was taken to Fittante taxidermy in Antigo. IIRC it cost my buddy about $3500 in 2010.

fwiw...I'm 6'2", bear mount is 3" taller than me.
This is a long process, could take up to 2 years to get it done right, depending on how busy they are, and good ones are very busy.
