3D Commercial Walkthrough & Renders

I have a commercial project that needs to be brought to life in 3D, covering every detail from the street-side façade right through to the last fixture inside. I need photo-realistic modeling, texturing, lighting, and a smooth animated walkthrough that showcases both the exterior approach and the full interior flow of the space. Here is what I am looking for: • A complete 3D model of the building’s exterior and every interior zone (reception, work areas, service areas, etc.). • High-resolution still renders suitable for presentations and marketing. • A cinematic walkthrough video (HD or 4K) that guides viewers from outside to inside, highlighting key design features and spatial relationships. • Source files in a commonly used format (3ds Max, SketchUp, Blender, or similar) plus any texture libraries so future edits remain possible. When you put your name forward, please send a detailed project proposal that outlines your workflow, the software you intend to use, milestones, and how many rounds of revisions you include. Links to a few comparable commercial walkthroughs you have already completed will help me see your style and quality. I’m ready to move quickly once I find the right match, so include an estimated timeline and any questions you need answered before you start.
