Develop cinema 4d (prefered) or 3ds file. This will have detail along the shaft upper right with the turbine blades and not much detail lower left with gears. In fact gear box can be skinned more to simplify. A propellor is needed to bolt on to left. I have additional cut away jpgs and 2d line art to awardee .
Bid is p/h. Software is 3DS MAX 6.1 Brazil. This type of hi-end 3d renders will take appr. 40 hrs to finish up nicely (without rendering) Man...that budget is hilarious, the only thing I can model for that is a pile of shit!
