I'll second Mark at Texas Landscape Creations. They could be a little longer to get you on the schedule though (maybe not) than some of the "smaller" guys.
Could not recommend Rafael. I contacted Rafael to cut my yard while we were out of town. He confirmed he would do it and even called to confirm again the day before. He never showed up and never called. I ended up having to cut over 2 weeks of growth myself
Met with Phil Anthony yesterday - working on moving forward with a quote he provided. He also quoted several other potential projects to help me budget for the future.
