Racing shirt

I am looking for a creative designer to help me create fan merchandise for a racing shirt. The design should be minimalistic with bold and graphic elements incorporated. My aim is to focus on adult sizes only but create something that will market the sport to everyone. The shirt should be eye-catching and professionally designed. Ideally, I would like to make sure that the design complements the aesthetics of the sport and appeals to a wide variety of custom audiences. I am willing to provide additional details about the project and the sport upon request to ensure the design of the shirt is successful. As such, please indicate what other materials or information you would need to develop the perfect racing shirt.
