Blender For Video Frame Mockups

I’m an independent artist looking for a Blender expert to create a cinematic frame mockup video showcasing my wall art. I will provide: - An example video showing exactly what I want (see attached) - The original Blender file used to create the example The example video consists of four shots: 1. Wide angled shot — Full gallery wall from a slight side angle with slow, smooth camera movement. 2. Close-up shot — Closer view of the frames and artwork, with the central artwork as the main focus. 3. Wide front-facing shot — Full gallery wall shown more directly, with subtle foreground movement from a sheer curtain. 4. Final hero close-up — Close view of the central artwork and surrounding frames with slow cinematic movement. The Actual Task: I want to recreate this same four-shot video BUT in a new interior setting and frame arrangement based on static mockup images provided (see attached). The final video should be photorealistic, with natural lighting, realistic shadows, smooth camera movements, and a strong focus on the artwork. This is initially a one-off paid project. However, if the result is good and you can reliably achieve the quality I’m looking for, there is strong potential for ongoing work creating similar videos in different interior settings. I’m somewhat familiar with Blender, so I would also like the final Blender file to be organised so I can easily replace the artwork and render new versions myself. That means the file will have to be reusable.
