I'm looking to procure a staircase with the following specifications: it should have 30 steps in total, with one side having a railing. The gap between each step should be 3 feet, and the height of each step must be 7 inches. Additionally, I require two guarders, and the steps should be closely bolted together for stability. Could you please provide a quotation for this product, including the cost and the estimated delivery time to Tehsil Jampur, District Rajan Pur, Punjab? Your prompt response would be appreciated. Thank you!
