New design for lamp project

Am looking for a designer to make me a couple of 3D design proposals for our new lamp... Attached is our current model for information. We would like to develop next generation, with additional features which will affect design... Those would be communicated later to awarded designer.

Final product aims to be 3D printed - DON'T NEED STL files at this stage, only HD visuals

For info, I personally work on Fusion 360...but I don't mind which software you use
