I can get this done for you. It makes me happy to see someone trying to help mother earth, and if I can help I'd love to be the person to design this for you. I've done tshirts before, but for the bumper sticker I was just curious as to how big you would like it to be. The final project is going to look great! I like the concept of what you've already come up with, and I'll make it come to life. I really hope to hear from you soon.
Thank you,
Nelson Design
