Designs for t-shirts..

I need some latest designs for the t-shirts which will be printed on the plan t-shirts. The design can be for any color t-shirt and I would like you to design such that it best suits that t-shirt color. Rules for designing: 1) Design your illustration in a vector art program such as Adobe Illustrator®. Or, design in a raster program such as Adobe Photoshop®. 2)If you are designing in a raster program, make sure you design actual size at at least 150dpi. 3)After completing the design save the original copy. 4)Take an another image of 640x640 pixel plain t-shirt (Of the color which you think best suits the design). 5)Transfer the design on to the plain t-shirt so that i can get a clear idea of how your design looks like. 6)Post me the original copy of your design and the t-shirt on which the design is being placed (Note:both in jpg format). 7)Once your design is selected you will be paid the amount and even more if the design is wonderful.
