Clear-cutting of images in Photoshop

Hi,? I have about 35 images that I need clear cut and send back as layered PSD and high quality JPG files.? The objects on photographs are on white background, so hopefully this won't be a too difficult task. ? The clear cutting has to be very precise though, so I wouldn't recommend using tools like magic wand etc.? I need these images supplied back within 24 hours of accepting the bid, so please bid only if you can start working on the project straight away.? I have attached a few sample images to demonstrate what sort of photos we're talking about.? Thank you.
