depending on the animation and the tools you use you can "reuse" animations either to a certain degree or 100%.
since this is a standard game character it could also use standard game animations from other models.

as said, the price is defined by the time you need and the quality and resources you demand and offer.

since med cant load animations you will need to import this model into another modeling package. now it depends if you can convert the file and presume the bones rigg so this doesnt have to be redone. if you cant you will have to either rerigg the model in the new tool or use med for animations.

if you need to find an animatior prepare one test file (model and anims list), share the files with possible animators and they will tell you how much they would charge in your case.
everything else is just guessing and wont help you at all.
