Interior realistic Render with D5/Corona

I need a photorealistic render of an interior space and I am open to using D5 Render, Corona, or V-Ray—whichever lets you achieve the most convincing materials, lighting, and mood in the shortest time. All modelling is already done; your focus will be scene setup, texturing, lighting, camera work, and final post-production.

Turnaround is urgent, so please indicate how quickly you can deliver the first draft and the final, polished images. When you bid, include links or attachments that show past interior work rendered in any of the engines above; this is the single most important factor in my decision.

Deliverables I expect:
• 2–3 high-resolution stills (4K minimum) showcasing the space from key angles
• Source file(s) in the engine you use
• One round of minor tweaks after I review the first delivery

If you are confident you can hit a realistic look fast, I’m ready to start right away.
