commercial rendering

I am looking for an experienced professional to help me with a commercial rendering project. Specifically, I need exterior photorealistic rendering. I have all the necessary details and dimensions for the project; I just need someone to take that information and create the renderings I'm looking for. This needs to be done with accurate attention to detail and precision and should match the desired style exactly. The end results should be level of quality suitable for use in a variety of commercial contexts.

This is actually a very simple job. I need to show a specific patio cover, being attached to a retaining wall, going over a pit stop for cars. Some basic photos of what I am looking for are attached, more details availabe as needed.
