Very nice. If you ever need some side work I'll pay you to do that at my house! Lol. I would hate to see what it might look like if I attempted a project like that..ha!
My labor would usually run about $2K, give or take, for something with this much detail. There is roughly $650 in material. It's very time consuming because you have to constantly level and plumb it as you go. I've built a couple of chimneys on custom homes that were over 50' high and were solid masonry. We charged $100/foot for a residential chimney.
I no longer fool with new construction and focus mainly on landscape or small jobs. I'll gladly do one of the outdoor fireplaces though. I no longer have the equipment or help to handle the big jobs.
