$40 - Face (mouth) Rig my Character (or use CC4?)

I have a blender character, and job is split into 2 parts:

$10 to correctly upload it as-is to my wonder studio account & be validated, no face rig or anything

And

$30 to give it a face rig (only really needs mouth because he has glasses) or use CC4 to redo the face if that's easier. Any way you like, as long as you validate it in wonder studio.

Thanks! Should be super easy for an experienced blender user
