Automotive engineer Suspension and beam

I’m looking for a automotive or structural engineer that can certify their drawings this project will require a lot of automotive knowledge and problem solving. I require a bolt in front beam to a kombi with double a arm or wish bone suspension set. This will require a lot of product search as the main components will need to be easily access able for the build and help keep cost down. It will also require a rack and pinion set up there for changing the steering set up this will also need to be modified as part of the project. I’m after someone with a passion for cars, some that understands the imports of the small things. At completion I will require all drawings, dxf, simulation images, cnc files, certification cert. please see images as this is A basic concept of what I’m trying to achieve
