I need to have someone to design Tee-shirt graphics, which will appeal to American young people. Graphics with vibrant colors, in various themes. Provide Photoshop .psd format source files, with each element in separate layer. Approx 10x12 inch size, 300 dpi. Please bid for two graphics. If we like more than two of your design concepts, we will buy all the designs we like. If we really like your designs, we will offer a contract to buy hundreds of your designs.
