image cut out

We have photos of the same type of product. The products are mainly black metallic with some grey and black matte surfaces too. The photos need to be cut from the white background so that the shadows have been removed. The products need to be cut out perfectly as the images will then be used for high quality print purposes. - 21 photos, hi-res - all photos have been re-touched - all shot on the same white background in basically the same position - products need to be cut out perfectly, shadow removed Please see the attachment for a sample of what the current photos look like. You will be provided with high-res images to work with.
