Photorealistic Instrument Renders Needed

I will supply a clean STEP file of a compact scientific instrument and need it transformed into a single, photorealistic scene that can produce three to five high-resolution stills.
The focus of each image should be the instrument’s overall design and structure, shown exactly as it would sit in a modern lab environment yet isolated on a transparent background so I can drop the visuals into web pages, slide decks, and large-format trade-show graphics without masking work.

Deliverables
• 3–5 UHD PNG or TIFF stills rendered from the same camera-ready scene, all on fully transparent backgrounds
• Lighting, materials, and shading tuned for realistic lab-style reflections and subtle shadows
• Final layered scene file (your native software or a neutral format) so I can request angle tweaks later if needed

Acceptance criteria
Images must look photorealistic when printed at banner size, edges perfectly clean against transparency, no text callouts, logos, or animations included.

If you typically work in KeyShot, Blender (Cycles), Cinema 4D, or similar GPU renderers, please mention it—speed and color accuracy matter to me. I’m ready to hand over the STEP file as soon as we agree on timing.

I have uploaded photos of the the prototype for reference.
