469887 Photos 100x - Add border + Fit to 51x71cm 2

This is the third time we have had to list this. Please only bid if you can do the below. I have about 100 images that need editing. They are all high resolution. The quality *MUST* be kept the same. Don't bid if you don't know about editing high resolution photos. Using photoshop/GIMP/etc; - the landscape pictures need to be fit onto a 51x71cm canvas. - the portrait pictures need to be fit onto a 71x51cm canvas. + they need an additional 2cm white border around the edges. Some images will not fit properly, and will need a small amount of cropping. Please crop the unimportant sections. Some images will need to be centered, with a large white border [squares for example]. We need quality work. We run a store and will have many more photos to do in the next week.
