Rendering of complex sketchup model for architectural competition

I am currently working on an architectural design competition and will need help with rendering a complex sketchup model. The model can be worked on any software you are familiar with, and it will need retouching and final modelling to achieve desired results. You will have to have demonstrable experience in architectural competition style renderings (photoshop, ambiance lighting, non repetitive trees, vegetation, people using the space, etc.) You will also have to be able to mount the renders within specific background photos and have the render show the exact context of the site. High resolution background images will be provided, for a total of 6 renders from specific viewpoints. Sketchup model will be provided as well. You will have constant feedback via sketches, textures to help achieve the desired result. Portfolio of work or samples of similar work is a must.
