Hi! I have a decade of experience in character rigging and technical animation(cloth, mel, python). I have also devised CG pipelines of some major productions. I can give you an advanced flexible character rig. Delivery time 2 days. The rig will have stretchy limbs, stretchy spine, isolation options etc. I can also give you support later. I also have some interesting pipeline ideas to speed up rendering and viewports.
Let me know. My bid is enclosed.
