NEVER USE THESE CRIMINALS! I contracted them for services in my new Office Building that I have worked so hard to open. It was the fulfillment of a dream to be able to one day open my own building. Long story short, I had to pay another contractor to come in and fix all of KOH's problems (the job cost me twice!!!!). After this disaster with these criminals, I learned from three of their former contracts that if you are not a Government or huge contract, they rush and brush you just to get the money and run! WARNING!!! NEVER USE THESE CRIMINALS!!!!!!!!!!!!!!!!
