Big Dog T-Shirt Design

Greeting Designers, I am looking for a skilled designer to create a t-shirt design for a group known as “Big Dogs”. Currently the client has a poor quality logo(see attached) and a motto that they wish to be incorporated into the design for the front (small left chest) and back (large centered) of the shirt. The motto is “If you can’t roll with the Big Dogs then stay on the Porch!!! The client has requested a pit-bull be featured as the centerpiece of the back design and if possible to include other dogs as well. The group has a few cooperate rivals (Cobras, Eagles, and a charter that looks like “The Thing” from fantastic four). All bids must submit a portfolio to show sample of your previous work. Please feel free to look at example of my request and to submit drafts to expedite the selection of this project. Good Luck As the designer if you have any other recommendations or ideas please feel free to submit an example for submission. ??Acceptable file formats include: .psd, .tif, .ai, .eps, .png, .pdf, .jpg, gif.
