Product Photo Background Removal & Touch-Up

I have up to ten product photos that need a clean, precise background knockout. Once the background is gone, I also want a light colour correction pass so the items look consistent across every file. Please deliver each image as a high-resolution PNG with a transparent background and crisp edges...
