Need someone in the Beulah, ND area to give me an estimate to install a 50,000 BTU garage heater. Will need to convert to LP from natural gas. (Parts came with the unit.) Also will need piping installed from existing LP line and shut-off valves installed. Will also need to be vented through wall. Had some surgery and cannot climb ladders or lift very much. Would like to get someone who has down this before. Thanks Brad
