For my project I reviewed some of the work that had been done by other designers and I invited them to participate.
Out of the 10 – 15 designers I invited only a couple accepted. GT Graphics was one of the designers I invited who kindly accepted and ultimately provided the winning design.
He is a very collaborative designer who will work with you to incorporate your feedback as well as providing you with ideas that you may not have considered. What I liked most is that he strives to provide a unique design and doesn't reuse concepts.
Even after the contest ended he agreed to make some minor updates to my design to ensure that I was a satisfied customer.
I have had three or four different projects like this and I would say that this experience was by far the best. I would seek out GT Graphics on future projects I am working on.
