Need professional CAD 2D/3D designer to design acoustic speaker cube

I'm looking for a professional CAD designer, who can create 2D and 3D models of a speaker. I have created a basic model of the speaker, need an expert who can use his creativity and experience to bring this product to the realization.

The speaker cube is around 9'' (L) x 8'' (W) x 9'' (H). I need the 2D/3D models of the improvised speaker design which gives the best acoustic architecture and suggestion on the best material to print and assemble the design. Finally, the design needs to be printable as per the specification required by this company https://www.ponoko.com/laser-cutting/wood/MDF.

Need this design on AutoCAD fusion 360 or SketchUp. The offered quote includes the complete design of 2D/3D models and further improvisations based on discussions.
This project needs NDA signed and need your confidentiality and openness to design the product.
