"Orion installed the buried electrical for our gate, in a difficult setting with multiple conflicting buried utilities in the same area. Other professionals had previously declined the work due to the complexity of the job. Orion put together a plan, and executed it well. He began the work promptly, and delivered on time. He provided receipts for all materials, which we appreciated, and gave us confidence in the final amount.
