CAD drawing of an inhaler device

I need a designer to turn my hand sketches of an inhaler device in CAD.

The device is not a complicated one. It has only 2 moving parts, which are a twistable nozzle, and a lid with a clamp latch as the locking mechanism. It looks similar to the example provided (photo 1). The outside materials are metal and wood.

The tricky bit, probably, is that I want to have some engraving patterns on the metal part. The patterns will include our logo and patterns that you would normally find on a luxury hunting riffle. Examples can be found here: https://www.purdey.com/guns-rifles/double-rifles.

Addition to the CAD model, I will need some really high quality rendered images, as this is for a customer presentation.

I also would like a contract in place to state that I'll own the work after it finish (unless it already states somewhere here), and you will not allow to share it without my permission.

Thank you for your interest.
