534516 Vector Images for T-shirt

I want to put 2 images on a t-shirt. On the front left chest would be the logo, and on the back of the shirt would be a large image. The back image would be about the size of a sheet of paper. 8 inches (width) x11 inches (length). I have the images already but need some modifications. I would want to take out the "save on top rated skateboards" text. It should have the link for my site in the red blotch using the white blocks. (My site would replace "click here". For the back image, I wouldn't want a rectangular shape. I would prefer the edges to be messy so there is no defined shape. I will send the images to qualified designers.
