Photo retouching - Ecommerce model shots

I need a photo retoucher to retouch 170 images and put them on a white background with some natural shadowing. The full-length ones also need to be aligned so they are the same perspective when next to each other on the site. They are currently on grey backgrounds, and the model needs slight retouching on the skin. I have attached three examples.

I need a quote to do all of the images. I would also like to see some examples of similar work.
