We have two fireplaces with brick fireboxes. We would like to add a more contemporary herringbone/split herringbone brick pattern inside the fireboxes. What specialist should we reach out to that can do this work? Is it even possible with an existing fireplace? Thanks so much, have no clue about fireplaces/would prefer our house didn't burn down :). We are located in Tucson, AZ.

Attached are photos of the current fireplaces as well as inspiration photos.
