Background Removal for 11-50 Photos

I have a batch of roughly 11 – 50 images that need the backgrounds taken out cleanly and replaced with a pure white backdrop. Edges should be crisp—no halos or soft fringes—and any reflections or shadows that don’t look natural against white should be removed as well...
