We cannot offer this kind of support included within our hosting packages. If you're having problems installing a particular script then refer to the documentation for that individual script. If you're still experiencing issues, then try contacting the author or community surrounding the script.
If you really really want us to install a script for you, and you can't do it yourself, then please let us know. We may charge you an administration fee depending upon the complexity of the script, though this would be arranged prior to script installation.
