Baseball Related Pin Designs

I'm in the process of creating a line of 1 1/4" & 2 1/4" "pinbacks" (aka "buttons") for promotion of a book and am looking for designs. I'm looking to pay up to $5 USD per design. The total budget on this project is $25, so that would be 5 designs @ $5 each. These designs should not violate any U.S. copyrights and/or trademarks. The designs should be sent as Adobe Illustrator files (see attached template). There is no limit on the amount of colors used. The designs can include photos as long as you're the copyright holder. The theme of the pins is baseball related. I will email the winning bidder specifics. To be considered, submit either a link to your portfolio or attach a few examples. Any baseball examples would be preferred. To clear up any possible confusion, I am NOT looking for web graphics or web "buttons". If you have any questions, PM me.
