AMA: My family owns a countertop fabrication/installation company. What do you want to know?

My family owns a small fabrication/installation shop (5-8 counters per week). Because a lot of discussion of countertops tends to happen through contractors or kitchen design shops, I feel like there isn't a lot of good information, or some outdated information, regarding counters.

Edit: we only do stone and quartz.

Let me know!
