8-2-13 Image sizing for large format print job

I need to have 23 images that need to be re-sized and placed into a single file for printing. We will be printing these on a large format printer with a maximum 42 inch print height. The items need to be sized to their actual dimensions (Provided in attached file) and placed into the file to minimize waste. The attached word document has the Qty of each item to be included and the dimension of each individual item. Some items only need to appear once while other items may appear 2, 4 or 6 times. The arrangement is not important, other than to minimize the total amount of print area, as I am charged by the total print area. In case you are curious, this will be used to create a 2D mock-up of a patient room headwall. So the items will be printed and then cut-out. I am printing it on a vinyl banner to make the pieces more durable. The deliverable will be a .PNG or similar file that I can edit and a .PDF that I can send to the printer. The items in the file must print as their actual size, so make sure each image is correctly sized and the quantity requested is correct. Thanks!
