AutoCad 2D & 3D models needed

Hello, We need for a client several AutoCAD models and designs for one new concept product, in several sizes and usage options. - 2D : outside and inside presentation of all features and components from side and on top. Second 2D model, we need with lines explaining what are the device functions and components located. - 3D : outside and inside presentation of all features and components in 360 degree angles; left side, right side, top and bottom. Also one version turned off and one turned on as it's something similar to a smartwatch. Thereby, all (turned on) software functions should be displayed, by showing an example interface per function. It should look as autocad designs, not too smooth that it will look like a fake like it's an existing product. We need several mockups, you need to save several times. We need a whole proces being saved separately, also every change. So it becomes a collection until the final design is matched. Let's say a story line of 2D & 3D autocad designs. We have as budget between 200-350$ for total package incl all files. Regards
