Who made that model?
As for doing you a favor:
if someone does it for you this time, you’ll still not know how to do it next time.
So better take this as an oportunity to learn rigging.
There are plently of C4D rigging tutorials on the web that show how to create a character rig,
adjust it to your model and weightpaint it.
Ofc. a T- or A-posed Model would be easier to rig (symmetry), but if you can manage to rig this one,
you’ll truely mastered rigging.
