I have been doing design work for over 7 years now. 90% of my clients are referrals some who have been with me for over 5 years.
All my graphics are custom made by me. If stock is used 99% of the time it is customized in some way by me, meaning the graphic is unique to your company. If I submit a design to your contest, the design is 100% customized and created by me for your company.
