Bobsled tractor scraper arm blueprint -- 2

I am seeking a freelancer to create a Bobsled tractor scraper arm blueprint to level the ground for bobsled tracks. I have a general size in mind, and a specific design but I don't yet have precise measurements, I just need the design cleaned up. My preferred medium for this blueprint is digital format. Upon completion of this project, I will require an electronic copy of the blueprint. The creator of this blueprint should also include any supporting sketches and drawings which are necessary for a clear understanding of the design. I am looking for a highly detailed blueprint for this project. I am seeking a freelancer who will have the required technical knowledge and experience to develop a reliable and accurate blueprint that will meet my requirements. I can provide the hydraulic sizes as well as the rough sketches.
