Best Ground Covers in Phoenix AZ

Price to play is a minimum of $5,000. Called for some general landscaping services, and I was added to the salesperson's schedule for them to meet and review my yard. Salesperson called a few days prior to gauge my project scope, and then steered me to a more generalized landscaper. While I'm sure I'll end up spending that or more on my yard, I'd prefer to deal with a single company that can spare the time to work on the smaller projects and can scale up to larger projects. It would also be nice if their website made it clear that they really desired only high-dollar high-roller projects.
