I'm very interested in your range of advertising light boards. Could you send me more details about the different models you offer, including specifications, available sizes, and customization options? Additionally, I'd like to know about pricing details and any bulk order discounts that might be available. If you have a catalog or examples of previous projects, that would be great too. Looking forward to your response!
