I'm looking for the perfect flyer to commemorate this important occasion

Hello, our pastor's anniversary is coming up soon and I'm looking for the perfect flyer to commemorate this important occasion. It means so much to me personally and to our entire church community. Our pastor has put so much labor, time, and soul into our spiritual leadership that I want to thank him in a special way. I realize that the flyer should be special - like the anniversary itself. But I, alas, do not have the design skills to create something truly unique. So I decided to turn to professionals.
