Clothing design for a new company called Eastward Threads. I want a creative design of a millstone on the back

I'm looking for a creative clothing design for my new company, Eastward Threads. I am specifically interested in having a millstone design on the back of a t-shirt, with an abstract style and a monochrome color scheme. I need someone who is creative and detail-oriented to bring this idea to life. As a small business, I'm looking for the most cost-effective solution without sacrificing quality or aesthetics. The completed design should be unique, so bring your best ideas to the table!
