Don't call if your job is small or expect good response.
Tony had great reviews and advertised as one who does yard conversions (Xeriscape), so we gave him a call for an estimate. I gave him approx. size of the job for my small front yard conversion. He came out, took measurements and such and said he'd e-mail me with an estimate. Surprised, when he said something like "I don't normally do jobs like this". It took a couple days, got an e-mail saying the estimate will be here this weekend...then never heard from him again!
