Urgent 3D Cantilever Gate Render

I need a photorealistic 3D render of a cantilever iron gate with railheads delivered before today ends. The model should capture realistic metal textures, clean weld seams and convincing shadows so the final visuals are presentation-ready for a client pitch first thing tomorrow.

What I will provide the moment we start:
• Exact overall dimensions and a rough sketch showing the gate’s general profile.
• Colour reference (dark anthracite powder-coat).

What I need back today:
• High-resolution still render (minimum 3000 px on the long edge) in PNG and JPEG.
• The editable source file from your preferred package (Blender, 3ds Max, Maya or similar) so I can make minor tweaks later.
• One clay render so structural details are clearly visible.

Acceptance criteria
• Proportions match the supplied dimensions.
• Railheads are modelled, not faked with textures.
• Lighting and reflections look physically plausible; no blown highlights.
• Files arrive before midnight in my time zone (UTC+1).

If you already have a material or HDRI library that speeds things up, great—let me know. Quick turnaround and clear communication throughout the day are essential.
