I'm looking to get more details on your prefab homes. Specifically, I want to know the pricing for different sizes and configurations you offer. It would be helpful if you could include any variations in materials, features, or design options that might impact the final cost. If there are any bulk purchase discounts or promotional offers, please share that info as well. Additionally, I'd appreciate it if you could provide an estimated lead time for production and delivery. Understanding your payment terms and warranty options would also be beneficial. Looking forward to your detailed response so we can assess the best options for our upcoming project. Thanks in advance!
