Post-Production : DCP Questions by Joyce Lao

My friend just finished his Feature, I am asking around to help him out. He is trying to convert it by himself for Theater distribution. He successfully converted it a few times but it's not quite there yet. He is asking if someone has an access to a Linux hard drive or how much does it cost? or if any of you have suggestions we can probably give it to someone who has done this before or any other software suggestions? We are in the Tri-state area (NY-NJ-CT). Thanks!
