Basic 3D Assembly Model in Autodesk Inventor

I need an experienced Autodesk Inventor professional to create a basic 3D assembly model for me. This model is intended for demonstration and training purposes, so it needs to clearly illustrate the assembly without unnecessary complexity.

All are sperate projects, except for the ones that start with "Gear", those are all one project.

Autodesk Inventor files are the finished product I'm looking for.
