basic geometric modeling to illustrate concepts in an academic paper

I am in need of some 3D geometric modeling to illustrate physical concepts in a technical paper. This will involve the creation of 3D models and rendering using software such as Autodesk 3Ds Max. The aim is to explain complex physical concepts through visual images, enabling a better understanding of the processes at hand. I am looking for someone who is proficient in 3D software such as Autodesk 3Ds Max. The deliverables would include 3D models and rendered images, as well as a description of the concepts illustrated.
