Design a T-Shirt

We here at ProLift are a start up garage door repair company that are looking to get a casual t-shirt designed for us that is "cool" (sorry for the lack of a better or more descriptive term). The front will have our logo on the upper left breast, but the back is what we are looking for some design help with. Our logo (included) is designed to look like a polished steel with a blue hue. Design-wise, we are thinking along the lines of having an image where our logo is stamped onto a sheet of steel (think "Ford Tough" plaque). Maybe a steel commercial garage door (which is what the "P" in our logo is tailored after). Perhaps that would be too busy though, and a steel plate of sorts would be more appropriate. We've included some images that we liked and would help show along the lines of what we are thinking. Another thought is to have the logo being freshly poured from molten steel. Utilize the blue color in our logo in place of the typical orange/yellow hue. We are certainly up for other ideas as well. We look forward to hearing from you with your proposals!
