Professionally made advertising posters

There is a man named Nick Crow, that I work with at church whom during a meeting I found out is a graphic artist. We were talking about my concert and he offered to help me with my posters. When it came time and after many tries of coming up with posters myself, I finally asked him for his help. He put them of a CD the correct size to send directly to the printers. I sent them to Staples and the posters were amazing. I offered to pay him, but he asked me if the concert was going to cost and when it told him no that I wanted it to be free, he told me that his service didn't cost either then. I will do something, but I must say, I never expected to have something so wonderful. Thanks Nick.
