Looking for vestibule contractor recommendations

I’m considering adding a vestibule (back?) to our ~1880s brownstone and looking for contractor recommendations. I’m having a little trouble since it’s complicated (carpentry, masonry, tile, electrical, etc.) but still not a large project.

Any recommendations would be much appreciated, especially from some of the similar recent jobs that folks have noted in other posts (e.g. https://www.brownstoner.com/forum/#!/general-discussion:building-a-vestibuleentryw).
