If you're looking for server setup services for the following on dreamhost:
please get in touch with me.
I have setup close to 75 youtube clones (some clip-shares, a few social media, ostube, alstrasoft, vshare and a couple of custom made scripts as well) on Dreamhost shared hosts and they work great.
I configure to make sure that the shared server resources are not overshot so you do not face the dangers of getting shut down by the host while at the same time the script works for you.
