MAYA LIGHTING, MENTAL RAY - I Need A Mountain Scene Lighted, Preferably In Mray

Industry: Art and Design
Design details: I have built a scene in Maya which I would like you to light up. I want it to look identical or as close as possible to the JPEG attached.
The entire scene is low poly. You can see examples of it, as well as further examples of what i'm looking for in the zip file attached.
I will be adding low poly models into the scene such as trees and hills. The scene sees a young man in 3 different environments, mountains, field and flying in sky. The scene runs for 1min.
I will create the sky in post, but i need someone to build the lights for the environments. I would prefer it to be done in mental ray and I will need the source file to be able to make adjustments.
There will be no texture maps involved, but you may need to adjust the shades of basic blinn and lambert materials.

The project is quite straightforward in that i want my scene to look similar to the samples I have shown in the attachments.
The full project will later run for approx 15mins and I hope to build a relationship with someone through this simple job so that they could take care of the entire project.
I would hope for the work to be done within a few days of project start date.

Thanks for you attention, and please feel free to ask any questions.
