totally depends on the modeller itself.
If you take one of the high quality artists of these forums here, let's say;
andvari, fuxerz or even Dan Silverman, you are looking into some serious money.
i'd say with so much animations, a requirement for skinning and texturing, dont look strange when someone would charge you about $500.
also, with all these animations in, and depending on your need (polycount, normal maps etc etc) you might be looking at a seriously big development time, before everything is completely the way you want it to be.

Then again, im no real artist, and these are only prices i am guessing (based on conversations i had with several artists with a similar question).
