    “Billy was absolutely fantastic. As an experienced businessman in my field I know better than to go with the lowest bidder, and Billy was not the lowest bidder, but he was also not the highest bidder, either. I selected Billy because he came with such great reviews. The reviews were all correct. Billy sketched my idea into a concept in just a few minutes, had a working Version 1.0 24 hours later, and with a few back and forths I had an application utility that my office will use for years to come. This utility will cut hours off of each report we produce. We were done in three days - astounding for a quoted ten-day turn time.”
