I am reaching out to request a quotation for 40 units of a specific type of ladder that I need. The ladders should be 14 feet in height and designed to be easy to fold and lightweight, ideally made from aluminum. It's important that these ladders are both durable and convenient for regular use. Please provide the pricing details, including any bulk order discounts, lead times for delivery, and shipping options available. Additionally, if there are any variations or upgrades that you offer for this product, I would appreciate that information as well. Looking forward to your prompt response!
