tinkercad design of a detachable kit for disables -- 2

I'm looking for a freelancer to help me design a detachable kit specifically tailored towards adults with disabilities. The kit will include wheels, handles, and safety belts, all made out of steel. I would like the kit to be durable so that it can easily help those with disabilities move around their home, or even outside. With your help designing this detachable kit, I am hoping that it will bring greater accessibility and convenience for those with disabilities.
