And so now it is all systems go. However, there is a small (I exaggerate.) issue of knowing the proper tools to achieve the desired results. Here are some key red-flags I have seen in my years of design. An Ad should never be created in Photoshop. Photoshop is for image manipulation, correction and editing. Just as you would never photo correct in Adobe Illustrator or illustrate in Photoshop (Although, I have seen this attempted.). While it is true that you can achieve the near the same results, it is the output that ultimately will tell the tale. If page layout is done properly in Adobe InDesign, the high-res output of a page should only run 2.5 MB to 5 MB. A full 8.5″ x 11″ Ad created in photoshop will result in a much larger file – in most cases at least 2x the size of a properly rendered PDF from InDesign.
