Both Native Trails and Elkay make a hammered copper sink like this. I would expect to pay around $2000 for this style/size.

Hi 6609brookside! We sell a similar double well copper farmhouse kitchen sink in a medium size (33" wide) and it's listed at $997. Our prices are very competitive because we work directly with our community of artisans and studios, with no middle man to mark up.
