Recreate our Design into a Banner Size

We would like you to re-create our existing design into Photoshop (or whatever application makes sense) specifically for a 32" x 80" banner size. In other words, we need it designed for this larger banner size (32 inches in width and 80 inches in height) so the quality of print looks very professional. Ultimately we will need a file (presumably a PDF file), that we can send to our local printer (who will take the file and print it onto the banner). Please note we love our existing design, so please try to recreate it (design it) to be as close as possible to how it looks.
