I'm reaching out to get some detailed information regarding the cost and logistics for an expandable container house, specifically a 40ft model. I'm interested in understanding not only the base price but also any potential additional costs we might incur, such as shipping, customs duties, and handling fees when it arrives in Quebec City, Canada. Additionally, it would be great to know the estimated delivery timeframes and any available options for customization or upgrades that you might offer. Any insights into warranty or after-sales support would also be appreciated. Looking forward to your detailed response so we can move forward efficiently!
