Bulk Background Removal Needed

I have a small batch of photos—between six and fifteen—that need clean, consistent background removal. All files are high-resolution JPEGs shot in studio lighting, and I want the finished images delivered as transparent-background PNGs while keeping the original size and sharp edges around every subject.

Please make sure:
• Edges remain crisp with no halos.
• No colour shifts or loss of detail on the main subject.
• Files are named exactly as the originals, just with the .png extension.

If you work in Photoshop with paths or layer masks that I can edit later, even better; include those layers when you export. Once the first image is done, send it over so I can confirm the cut-out style before you complete the rest. Looking to start right away and wrap the entire set quickly.
