Today I have started to put together a soundscape for my project. I have been downloading sounds from freesound.org, and layering them in my rough cut sequence.

This soundscape is inspired by David Lynch, especially Eraserhead and the industrial soundscape of that film. If you can be bothered, this is the original soundtrack for Eraserhead, but even just listening to the first minute you see the resemblance.
