Replace Backgrounds With House Driveway

I have four high-resolution photos that need a complete background change. The subjects must stay exactly as they are; only the setting behind them should shift to a realistic house façade and driveway of your design.

Here’s what I’m after:
• Cleanly remove the existing backgrounds without affecting edges, hair, or fine details.
• Composite each subject onto a new custom scene that shows a welcoming home exterior and driveway. It should look like the originals were shot on location—correct lighting, shadows, and perspective are essential.
• Return the final images in both layered PSD (so I can make tweaks later) and flattened JPG/PNG at the original resolution.

Please use any professional tools you’re comfortable with—Photoshop, Lightroom, or equivalent—as long as the results are seamless and photo-realistic.

When you reply, a quick note on similar composites you’ve done will help me judge fit. I’ll provide the four source files and reference shots of the house/driveway as soon as we start.
