Photoshop photographs into catalog ready images

We have 38 images that we want turned into catalog/website ready images. We have digital photography taken for 38 images. The project doer will take these images, photoshop them, remove the background, make the bottles round, alter the colors if needed, and send them back to us in photoshop with the clipping path saved, ready for catalog/website use. We want these sent back to us in a 4320x3240 photoshop file which should be the standard photoshop size. I will send you one test picture to photoshop so that we can see what you can do.
