3D animation

We are working on a tree climbing metal device that we have designed in CADCAM (STL, STEP, IGES) and we need to simulate the detail of the process of climbing the tree with this tool similar to this video [login to view URL] We will be adding various safety (harness etc.) as the logic is to make a modern system for industrial use Animationb should basically show a man climb on the 2 frames and once mounted on the 2 frames he climbs by pulling one foot then the other and climbing this way this animation is to be used for a technical instructional animation as well as for identifying safety weakness and pressure on metal (as frames are under prototyping) so we need an expert in industrial animation that can work on this project immediately.
