CAD Designer consumer product - 3d model & engineering drawings

Hi,

I'm looking for a CAD designer to create a 3D model and engineering drawings for a physical product - a modular shoe lift attachment (similar to the EvenUp shoe balancer).

I have a concept image and full technical specification document ready to share.

What I need delivered:
- 3D model in .STEP format
- Engineering drawings in PDF with critical dimension callouts, material callouts, and a basic assembly drawing showing how all components fit together

Reference size is UK 8. Main materials are rigid TPU/plastic, flexible TPU, and EVA foam.

Please only get in touch if you have experience with physical consumer products involving plastic or TPU components.

Thanks
