Not sure of your budget but ProjectSAM's stuff is right up your ally.
This sounds fantastic, unfortunately its way over budget, i couldnt really justify spending any more than £120 at the present time, its definitely something ill keep in mind for future projects though. As for the DAW, I'm running windows, so im not sure i would be able to.
I had a quick go at making something on audacity using samples of stuff and fiddling around with them a little. Would you mind telling me what you think?
I tried to get back to the eerie theme, and i think it came off pretty well

EDIT: Ive just looked at the sticky thread on DAW's, ill have a more in depth look in the morning but they seem pretty good and some of them are in budget too, thanks for the heads up!
