Blender Roii Bus Modeling

I need a clean, well-proportioned 3D model of the Roii autonomous bus built entirely in Blender, following the reference material shown at https://autoa2z.ai/ROii. The model will be used for concept presentations and system-level visualisations, so ultra-high, production-ready detail is unnecessary; what matters is that the shape, scale, and key functional elements read clearly from every angle.

Scope in a nutshell
• Exterior: replicate the core body shell, then add mirrors, lights, side panels, doors, wheels, and trim so the vehicle looks complete when viewed close-to in renders.
• Interior: block in a believable seat arrangement and general aisle layout (no need for fine textures or a full cockpit).
• Proportions: match real-world bus dimensions as closely as practical to keep the concept believable.
• File delivery: native .blend plus a clean FBX (or OBJ) with all meshes named and grouped logically.

Acceptance check
1. Model opens in the current stable release of Blender with no missing assets or modifiers.
2. Polycount stays reasonable for real-time use (exact target can be discussed).
3. All requested exterior and interior elements are clearly identifiable in a clay render.

Let me know if this scope is feasible for you, along with a ballpark timeline and cost estimate. If you have previous vehicle work in Blender, a few screenshots or portfolio links would help me gauge fit.
