I'm looking for quotes on various sizes of greenhouse tunnels that you offer. Specifically, I'm interested in understanding the different dimensions available, as well as any material options and customization features you may provide. Could you also include information on pricing, lead times, and any bulk purchase discounts? This will help me make a more informed decision for our upcoming project. Appreciate your help in getting this info together!
