Where can I find commercial free human bases? (Rigged, no texture, simplest)

I need a test character model for my project and I need a basic COMMERCIAL FREE human base that has no texture, rigged, and the simplest model (ex: no big muscles, face features except nose and mouth or no mouth at all, simple feet no toes, just a standard MALE) I think I maybe asking too much but if you know any sites/models, please help me. Thank you.

this should work for your needs i think
