Utility Product Design Blueprint

I need a skilled product designer to turn my utility-focused idea into a clear, build-ready blueprint. The job centres on product design rather than prototyping or mass production, so I’m looking for someone who can:

• Translate functional requirements into a workable concept
• Produce detailed sketches and 3D CAD models that illustrate form, fit, and usability
• Specify materials and basic manufacturing methods suitable for efficient production

I will share my preliminary notes, target user profile, and size constraints once we start. What I need back is a comprehensive design package—drawings, native CAD files, and a concise bill of materials—that an engineer or manufacturer could immediately use as a foundation for prototyping.

Experience with utility products, ergonomic considerations, and cost-effective material selection will be highly valued.
