deck design

I am looking to have a large outdoor deck designed for outdoor dining. It will extend the size of the living space by about 10 feet, add large sliding glass doors, and connect the lodge with the pool area and yard. I am looking for a deck with a composite material, as it is both durable and pleasing to the eye. I am looking for professional help to ensure that the design is exactly as I envisioned, and that it will also stand up to the typical weather conditions in my area. I appreciate any help and advice that can be offered. Thank you for your time.
