I highly recommend Gerrior Masonry. They rebuilt my brick and blue stone front stairs last fall; the work is beautiful, the price was exactly as quoted, started and ended on time, and the masons were a pleasure to have around. What I appreciated most, though, was that the owner took time to walk me through several options including materials and design, and clearly considered the usage of the stairs in his recommendation (eg, my stairs make a turn, and we measured out different widths of stairway to find a balance between cost and accessibility on the turn). I'd say you should at least talk with them early, as they will give you a good basis for judging other quotes. Good Luck!
