We used Premier Grilling to build ours in 2020. Received bids from 2 or 3 other places. They weren't the cheapest but weren't outrageous either. All in the same ballpark. Ultimately went with them for 2 reasons.
First - they have a store a couple of miles from my house so I could go make an ass of myself if necessary (wasn't necessary).
Second - they were a one stop shop for any warranty work since the equipment was purchased from them as well. The other contractors told me to buy what I wanted and they'd install.
No complaints that I can recall. They did what they said they'd do, when they said they'd do it. This was before supply chain issues really started to hit so I think our kitchen was started within a month of contract at most. No massive structures, just cabinets/counters at each end of the patio with some equipment (Evo grill, fridge, drawers/doors/garbage bin). I don't remember the exact amount of time but it couldn't have taken more than a week since they weren't building any roofs, running plumbing, etc.
Take the trash out staff.
