Create a CAD drawing of my small object 40mm cubed

I have a product around 40mm cubed. It is plastic extruded. For confidentiality reasons, I can’t show it until the job is awarded. I need to get it captured in CAD so that I can modify and upgrade it. Then I will need to get the new revised object 3D printed (by others). I will provide close ups from multiple angles and measurements. You will draw the CAD drawing precisely. I will advise you of the changes I need made which you will implement until I am 100% satisfied with the revisions. You will then by way of a milestone, give me the CAD in a common format that I can get a prototype 3D example printed. After this there are sure to be one or more revisions you will need to implement. I have CAD and I have 3D printers. But I don’t have time or sufficient expertise to do this myself. I seek experts to assist me.

You will be a very skilled CAD operator with specific knowledge of items for plastic extrusion. The purpose of this exercise is to get a mould made for the new product. Please quote your price.
