Create Custom Wooden Shelving Unit for Home Gym

I need a skilled carpenter to design and build a custom wooden shelving unit for my home gym. The unit should be approximately 6 feet tall and 4 feet wide, with 5 adjustable shelves. The material should be sturdy and easy to clean, and the unit should be able to hold a minimum of 200 pounds. I'd like the design to be modern and sleek, with a neutral color scheme that blends in with the existing gym decor.
