At these prices? No. A hosting company that provides that level of hand-holding should charge ten times as much, or perhaps even more.
I can't find the terms of service anyplace, but at one time, it said that by signing up for service, you acknowledged that it takes certain knowledge and skills to use a web hosting service, and that you were asserting that you had those skills. Dreamhost techies tend to do more than they are supposed to, but one wants to be careful not to ask for too much. There's the story about the pitcher that made one too many trips to the well....
Actually, installing routine scripts is something you can easily learn to do for yourself. Get a copy of ActiveState Perl (it's free) and install it on your PC so you can check the script for the syntax errors you generate while customizing the script. Upload the script in ASCII mode (or edit it in UNIX mode). Set the permissions on scripts to 755 and on data files to 644. That's about all there is to it.
If you aren't capable of handling that, hire someone to install the scripts for you. It should cost about $35 to install the average script.
