Graphic designers are all about the creation of a project. We are rock stars in that area. The best way to help in this process is to review - thoroughly - all proofs that are sent to you for your order. It would be great to say that we'll catch everything, but we need you to be that second set of eyes and, of course, when it comes down to it, you have the final say on when it goes to print. So, check twice (or three or four times) and print once.
If I can help a business owner create the brand they're looking for, my job is done.
