My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.
We carry a few similar looking fixtures on our website. These ones look like they may be the Hampton C1 Pendants by Hudson Valley Lighting. You can follow the links to the product pages to take a closer look and get more information. Hope this helps!
