3D Model Comparison Drawings

I am in the sales and marketing group of an electric motor company. For this reason, I am looking to hire assistance in creating 3D model comparison pictures that will be used for sales and marketing purposes. The drawings will show our motor on a machine and side by side comparison to a competitive type motor on the same machine. The purpose is to show how my motor is much smaller compared to the competitive model. I see this as an 3D model type drawing being shown in 2D. An example is attached where we have created a comparison on a vertical pump application. The requirement is to create the drawing of the machine and then add our motor which we can provide the 3D model and then create the drawing of the competitive motor based on a real motor and then combine the machine and motor. There are four comparison drawings that I would like to have done: 1. Motor assembled to a conveyor drive that includes a baseplate, gearbox and coupling. The motor and gearbox are shown mounted on the gearbox and the coupling is connecting the motor to gearbox. 2. Motor assembled to a centrifugal fan. This is similar except the driven machine is a large centrifugal fan. 3. Motor with a direct drive cooling tower fan mounted on the shaft. The motor is mounted vertically up with fan on the shaft. 4. Motor mounted to a horizontal centrifugal pump. This would require a baseplate and pump drawing as well. I can provide illustrative examples of each version. The requirement is to create the drawings of the machine based on real dimensions that we can determine and combine the motor and machine in side by side comparisons. The attachment is a perfect example. We already created this one and one to create similar for other applications as described above. Thanks.
