ADDING A GREY BORDER TO OUR IMAGES - repost 2

looking for someone who is able to add a grey boarder to our photographs. We will supply images - we need then some to work on the job within 24 hours. I have attached images One without a grey boarder and one with. The same grey boarder must be placed on the 'without' image. We will have roughly 1500 / per year and will most likely send 25 images to be completed at any one time. I would prefer a fixed price per image.
