Design a T-Shirt

Create a design in vector format for my shirt line, consisting of one certain, specific form of "sea life" including -snook, redfish, or tarpon in it's habitat (mangroves or in a feeding frenzy). I also want the design to contain the name "saltwater convict" in my registered trademark form as attached. If you are able to make the logo look more appealing I am open to suggestions, however the "loops and hooks" of the name must look like fish hooks as in the sample picture. I also want a duplicate of the Saltwater Convict logo, so it can be put on the sleeve. Another thing I am open to is to have the picture theme incorporated with the logo (make the fish look mean, what you picture when you think of saltwater convict etc) . Examples of what I am looking for are also attached. The design will be used to be screen printed onto t-shirts, and need to be the correct size etc to do so.
