I went with more of a modern sports-tech look. I found that I feel an appropriate font for your company. You can find this font at Adobe Typekit. It's called Sneakers-script-medium. What I did with the lettering of "SUTER" was I connected the letter S to the U and then the U to the T and the T, E, and R are also connected. I used the Swiss cross as a icon for the logo. I used red, dark blue, green, and silver. I also made a back and white background version. The last thing I did was added a T-shirt mockup so you could see what it would look like on a t-shirt.
