Bulk Photo Retouching / Editing for Animation

We have approximately 50 pictures that require editing. We need a portion of each picture removed and then have the background shaded and blended so as to appear seamless. The pictures are all similar in content and need the same aspect removed from each one. We have a few sample pictures attached. You will see from looking at them that we need the copper screw at the bottom of the object removed, as well as the shadow and reflection so that it does not look as if anything was taken out. These images are going to go with a group of other images to create an animation in which the products will be viewed from 360 degrees. This means that the shading and shadowing must work from every angle. To anyone bidding, please edit one of the images and attach it to your bid so that we can gauge your skill level and ability t complete this project.
