Alter some Images

We have about 500 images that need to be photo-shopped to allow them to be uploaded onto corporate websites where they will be offered for sale (like ebay and amazon). They are photographed raw and then need to be touched up and photo-shopped. Important that the quality of work be up to our acceptable level. Attached is an example of a before and after images. These examples are what the images will be like when we send them to you and what they must be like when we get them back. We used the White Balance Eye Dropper in Camera Raw to adjust these pictures + other select photo-shop filters. We have maybe 300-400-500 images that need to be done. We would test your work on the first 30 or so. We are looking to pay you per image photo-shopped.
