After attempting to locate the official website for Benchmark Fence Co. through the provided URL and web searches, I was unable to find a valid and authoritative source. The provided URL was invalid, and web searches did not yield a verifiable official website. Without an official website, it is impossible to extract the necessary information to create a factual and neutral description of the company's services, service area, history, or unique value propositions. Therefore, I cannot provide a long description.
