Looking for people to join built a human carrying tank base

I’m looking for a free lance robot builder who can help engineer and built electric powered rubber tank track base that can carry a 160 pound human. We are already engineering it in 3D, but we don’t have enough experience engineering for this particular field. We’re based in LA.

Unfortunately RobotShop does not provide these services, but hopefully someone from the community might be in a position to help.
