Taekwondo School Logo design

I currently run a mixed martial arts school (MMA). The website is www.tcbfightteam.com. The name of the gym is TCB (stands for Taking Care of Business). As you can tell by the website the graphic for the MMA part is a pit bull. We have recently added the TCB Taekwondo and would like to create a logo that can be used in conjunction I have attached some example of what we attempted. I am looking for somoneone who can help us create a logo that is black and white. We will be putting it on T-shirts, uniforms, etc. Taekwondo is a kicking sport so, that could give you some ideas? I need it to be clean and represent the group. The winner of this project will need to provide high resolution files to use for printing t-shirts, etc as well as a smaller version of the logo for web usage. They will release the image to use for full usage. In order to win this project, given it's not a hard project I would like to see demos of what you have in mind based of the criteria I have given. If you have the best solution I will award early.
