I need a landscape designer

This is not so much design but to make a very simple 3d arena (to be used in sketch-up and such) To make so called previs for filmprojects. Basically we have a location and we want it in the computer to understand angels etc. Does not need to be other than unrendered surfaces with colors to understand the material. Essentially the use is a simple 3d storyboard tool. To create camera-movements. This is not to be high end in any way. Functional.
