We used Mullaney, a neighbor of ours used Savanna. Some of the companies I talked to did not want to do what I wanted, IE: flagstone would look better, let's not do pavers, sort of thing. One also said, let's not demo the existing concrete, we'll just put stone over it.
Mullaney was the only one who said yeah, let's demo the concrete, we'll pull water from the main line and even switched up some of the hardscaping materials when we saw something we liked better. They changed out some of the tile pavers that I thought didn't match the color pattern (slightly darker) and fixed a couple of the stone caps that also looked a little darker than every thing else. Mullaney did come in at few thousand more than all other quotes, but we felt comfortable working with them, they addressed all our issues, and he was responsive to what we wanted. One negative - it did take longer than what he initially said, over 2 months when he said it would only take a week to 2 weeks, we have a small yard...it shouldn't have taken that long.
