ufo lamp 3d model

I want a lamp shade that looks like a cartoon alien ufo with little aliens inside the cockpit. No dome on the ship just a full open top so that I can add an acrylic top later. The ufo is silver with rivets around it. The ufo has little legs for landing gear. The aliens are green life like greys. The lamp shade should be fitted with a mount to secure regular standing floor lamp and have the proper mounting bracket for the light bulb to screw into. The position of the mount should sit in a way that depict the space ship hauling the bulb inside behind the aliens.
