I don't remember the op mentioning if this was a viable sales piece, hell nothing sells enough to make up for the time and effort it takes to create something...you do it because you want to.

I find the modeler should usually also be the rigger. That way they know how the topology should flow and what pieces can be correctly rigged and what pieces should just be morph targets, etc, etc. It can be done on a "hired gun" basis but again I find that the person who commits the time and effort that it takes to model something also commits that same time and effort into rigging.

Comitted to excellence through art.
