Therapeutic Dimensions - repost

I would like to keep hosting with Dreamhost & I am trying to find a developer to convert software for my website. Task: post software is as follows: nginx, postgresql, rvm, and unicorn. My current developer doesn't have the skill or inclination to do this work. "DreamHost has gone against the standard, Unix filesystem layout, and added a custom /dh path, under which they have put the various server software that they support. These are wired into the system in such a way that, to go back to using the distribution's own server software, I would have to manually reconfigure all the links"
