I'm interested in purchasing greenhouses and would love more info about your available options. Could you please provide details regarding the types of greenhouses you offer, including materials, sizes, and any special features? I'm particularly keen to understand the customization possibilities. Additionally, it would be great to know about your pricing structure, lead times for delivery, and any bulk order discounts available. If you have a catalog or specification sheets, please share those as well. Looking forward to your prompt response with the relevant info!
