The project’s cost is determined by the size of the project and the scope of work involved, which can range from $100 to $5,000. For a single-trade residential project, the cost is approximately $150. However, if the project involves all trades, from the groundwork to the finishes, the estimated cost could be around $800-$1000. Additionally, for multi-story commercial building projects, the estimated cost could be as high as $2,000.
