Photo Editing involving moving bodies in photo

It is a high quality professional photo that will be used for the cover of a magazine. It is of 5 people, vertical. One of the people needs to be moved over about a centimeter toward the center and the other needs to be tilted so he feels more a part of the photo. All are wearing black which makes it a little easier with editing. Needs to move the body parts and make sure arms and hands still look real. No new limbs will need to be created. Shine and wrinkles on faces also need light retouching.
