I hope this message finds you well. I'm reaching out to request a detailed quote for greenhouse specifications that align with our operational requirements. We're looking for various options that include different sizes, materials, and features. It would be great if you could provide information on your available models, along with pricing tiers and any bulk order discounts that might apply. Additionally, could you please include details on lead times for production and shipping? We're particularly interested in understanding the warranty and after-sales support you offer, as these factors are crucial for our decision-making process. Any brochures or catalogs that illustrate your greenhouse solutions would also be appreciated. Looking forward to your prompt response!
