URGENT: Product Photo Touch Up

We have a product to be listed on a major portal and we need a high quality professional photo for the site. The product is a DVD set, which has a case that contains 10 DVD's. We have a number of photos of this in different arrangements. They are all high quality and taken on a good camera, to almost professional standard. We need the photo edited / touched up to look like a highly professional product photo including, removal of the background to make it white. Also, the product needs to take up the majority of the image. IMPORTANT: We need this job carried out immediately, ie. started and completed today, preferably within the next 6 hours.
