There are plenty of graphic artist within the crowded market. If you have not found one yet, then ask a friend, family member, or stranger on the street. Chances are one of them will claim to be or know a graphic designer.
The right artist should not only be creative, but they should also understand how to create artwork that is marketable. Designing is the easy part, but knowing what to design, who to design for, and how to direct, entertain, persuade, and attract attention with your artwork is the difference between having good artwork and effective artwork.
