I'm planning to convert a large aluminum structure into an outdoor display screen. The dimensions of the structure are approximately 8 meters in length and 2.5 meters in height. I'm looking for a solution that can effectively transform this into a robust and weather-resistant screen suitable for outdoor use. Could you provide me with an approximate quote for this project? It would be helpful to understand the cost involved in both the transformation of the aluminum structure and any additional components or technologies that may be required for optimal performance. I'm particularly interested in the durability and visual quality of the final product, so any recommendations you have in this regard would be appreciated.
