Photoshop a range of photos of a product to extend the background, remover creases and generally improve the pictures.

We have a folder of around 100 images taken from a photoshoot we wish to use for website/marketing/sales material. We would like someone with photoshop experience to extend the background, remove creases and improve the image quality of around 50 of the best images. We have videos of the product on a lazy suzan, we would also like a rotating GIF produced with a transparent background.
