outdoor floating staircase

I am looking for a skilled contractor to construct an outdoor floating staircase for my property with a modern aesthetic and a metal material preference. The size requirement is up to 20 steps. The staircase should be durable enough to withstand the elements while also meeting the visual standards I am aiming for. The metal material should be aesthetically pleasing, and the design should be precision crafted to fit in with the modern aesthetic I am seeking. Further, I am looking for a contractor who can be thorough in ensuring the construction is reliable and able to handle regular use. I am expecting high-quality craftsmanship in the construction process and a contractor who is willing to work with me through each step of the process from design, engineering and permitting.
