I need a graphic designer

I'm looking for a design identical to the front and back of this tshirt I will attach with a few modifications. Instead of a tiger, it has to be a crocodile. But the level of detail of the design has to be the same. At the back instead of "American Thunder", I need it to say "Nostal" where the word "American" is, and "Cart" where the word "Thunder" is. In the middle, once again I'll need a crocodile similar to the type of the eagle.
