Design a banner/brand

I am opening a gym soon, so very tight budget. The gym is called "Cincinnati Meat Locker" which is a vague name. I am really looking for an image that will incorporate our culture, the gym, and the name into an image that is powerful, not cheesy/corny, and creative. I am thinking something like: A garage door type image opening (we have one in our gym). Inside the garage door is darkness and you can see the silhouette of a girl doing a front squat and a guy doing a deadlift (like in the silhouette images attached). This automatically creates the imagery that the "meat locker" is a gym. We are creating imagery and associations in peoples minds. I have had a few mockups of this concept and everyone makes things that are extremely cartoon-like or corny. I want to avoid that. We are a serious gym and a serious environment.
