Mechanical Device Concept Sketch

I’m developing a brand-new mechanical device and need clear, expressive concept sketches that capture its overall form, key moving parts, and assembly logic. The product is still in the early ideation phase, so your drawings will guide both engineering and investor discussions.

Here’s what I’m after:
• A series of detailed concept sketches showing the device from multiple angles, with exploded views or call-outs where motion or interaction needs to be understood.
• Digital delivery in high-resolution PDF or layered PSD/AI so I can annotate and iterate easily.
• A short round of revisions once I gather feedback from my partners.

Traditional hand-sketching skills are welcome, but I ultimately need clean digital files. Familiarity with mechanical design principles is important so proportions and clearances make sense, even though exact tolerances aren’t required at this stage.

Please share samples of similar mechanical concept work and let me know roughly how many sketch pages you’d include in your initial pass. I’m ready to get started as soon as I find the right fit.
