Looking for ready-rigged models

I have tried rigging human-like models & made them walk or jump.
But they don’t look smart enough or behave realistically.
So I have given up rigging.
I am now looking for human models (male & female) that are already expertly pre-rigged rigged and preferably clothed.
I’d like to buy a few and then use them to walk, run, dance etc. (in Blender only.)
Where is a good source for rigged models please?
