I would agree that it isn't hard to do. The animation would be uncomplicated, but you would have to find someone that knows compositing and get the transparency on the block of ice right. Blender is a versatile program, but you do have to know some advanced techniques to do what you're trying to do and at a satisfactory level of quality. If I were to do it (and I am a student), I might ask for at least $70 to do the modeling, texturing, and shading of three objects, along with animation, rendering, and compositing into live-action footage (also need HDR images provided from the film set). Main point is that finding a student that is capable in every area is not likely, and you should realize that someone might create good models, but not have skills in other areas.

Hope this helps.

It is better to do one thing well, than to do many things and excel at nothing.
