Motion Simulator redesign Project

Hi All, I require someone to help redesign the first prototype which has been completed into the next version. The initial work will involve modifying the current design with a new top yaw section. 99% of new design elements required have been found, just need an experienced mechanical engineer to look at the design and make it all work together. Assessing the COG, stability plan out how to attach the new parts to the current build. I do require someone local in my area of Brisbane Australia as I prefer you come and have a look at the actual project and a NDA will need to be signed to protect the IP of the work. Cheers and any questions please feel free to ask. Thanks
