CAD Product Prototype Design

I have a complete set of performance and dimensional specifications for a new product and now need it turned into a fully realised digital prototype. The scope is strictly product-focused—no architectural or mechanical plant work—so everything you create should lead directly toward manufacturability and user testing.

Here is what I need from you:
• Translate my written and hand-sketched specs into a clean, parametric CAD model (SolidWorks, Fusion 360 or similar).
• Provide native files plus neutral formats (STEP/IGES) so I can pass them to suppliers.
• Generate high-resolution renders that clearly communicate form, material and assembly intent.

Acceptance criteria
• All critical dimensions, tolerances and fit-ups captured in the model.
• Assemblies organised with logical naming and exploded views for clarity.
• Files open error-free in the latest SolidWorks viewer.

If you have experience taking a concept through to a digital prototype and can work iteratively with quick turnarounds, I look forward to collaborating.
