Graphic T-Shirt Business Needs Creative Design for Shirts

This is what a business in Canada was looking for in their t-shirt design

I run a website called RunExpressions.com where I sell moisture wicking t-shirts aimed a people who run. My objective is to provide words / and or graphics that will inspire and motivate those people.

I need a creative catchy graphic capturing the image of "kick ass." I have a vision of a iackass aka donkey flying through the air after being kicked with a footprint from the bottom of a running shoe on it''s butt.

I would like the graphic in both vector (.eps) and .png format and it must meet the guidelines here:
