Design a T-Shirt

I'm looking for clean simple designs for expanding lifestyle/streetwear tshirt line with designs leaning toward typographical elements (typography) with a positive vibe. Looking for an experienced artist who may be willing to stick with and help grow with the company. If interested please contact me through email with a short letter of interest, previous work samples and to get more information on subject matter, inspiration, and company information. Must be able to produce clean ready for print art. Illustrator format, or PSD format. Please separate the colors per layer. (IE: all green would go on one layer, blue would go on a second layer,etc...) Budget is approximate and dependent on complexity of art.
