Best Ceiling Drywall Installation in Phoenix AZ

First, let me say that he came out and did an estimate right away and seemed incredibly knowledgeable. I was so excited to hire this company to remodel the kitchen in my mother-in-law suite. Unfortunately it took two weeks to get the initial estimate rather than getting it by the end of that first week as he had stated. Then the estimate was missing some major components... The install of a gas stove and stainless hood (and that's really a BIG part of this project).
When I emailed him about this, a week later I still had not heard back with an updated estimate so I emailed him yet again and left a voicemail. His response was that he thought the vendor would install yet he and I had very clearly discussed that Dynamite would do the installation. Bottom line is that he added another $250 to the estimate and still didn't give me any info on his availability (which I asked for a few different times). As much as I would love to hire this company because I really genuinely think he knows what he's talking about and the price is reasonable, I think he is just far too busy and may not do a good job on my project because he didn't care enough to get me the estimate when he said he would, missed major components on the estimate, didn't  respond to my email for over a week, and he also didn't  answer his phone or return my call. I know my project might not be as big or important as his other projects, but it is very important to me and I would have been happy to schedule this several months out if needed. I just want a company that I can count on to pay attention to detail and communicate in a timely manner. Very disappointed this didn't work out.
