Zalmy KavkaFounder, ZK Builders

""I love, the personalization of it. You get it more directed towards the contractors that we need. You, make it a little more personal than putting it on Blue Book or Planhub or anything like that. You let us communicate with the subcontractors, so we can narrow it down from what you've already narrowed it down from. We get more, more specific, more detailed quotes, more the correct quotes that we're looking for from you guys as opposed to maybe other places.""
