Physics-Based Hand Locomotion System with Climbing and Object Grabbing for VR in Unity

I am looking for a freelancer to develop a fully physics-based hand locomotion system optimized for VR in Unity (version 6000.4.0f1). The system must exclude joystick locomotion and rely entirely on hand-based interactions... (Budget: $30 - $60 USD, Jobs: Android, C# Programming, Game Development, Mobile App Development, Unity 3D)
