White Background Photo Editing

I have a batch of product photos that need their current backgrounds removed and replaced with a clean, solid white backdrop. No other retouching, color grading, or graphic overlays are required—just crisp cut-outs on white so the items look consistent across my store and marketing materials. Please return the finished files at the original resolution in both JPEG (for web) and layered PSD or PNG (for any future tweaks). Accuracy around edges and natural-looking shadows are important; I work in Adobe-based workflows, so Photoshop-compatible results are preferred. Let me know your turnaround time and any image prep guidelines you’d like me to follow before sending the files.
I also have needs for some photo editing - mainly changing table legs or other modifications to photos.
