3D Modelling of a reciclyng plant.

I have the blueprints for a garbage-disposal recycling plant. The idea is to model the plant as it's represented in the Auto cad blueprints. Just the modelling will work fine. Only the outside of the plant is necessary, not the inside. The model should be done in not more than a weeks time. The terrain is not necessary, textures aren't necessary nor is the lighting. This is a confidential project, so please don't share any files with anybody.
