Hi.
I am actively developing and maintaining projects in Sharepoint 2010/2013 and custom solutions around with them. Large amount of tasks involve writing PowerShell scripts - working with items (just getting metadata from few or updating hundreds of thousands), managing WSP solutions, gathering all kind of information from SharePoint project (like Your desired script from link) and etc.
As you described in offer, you have a script, but it is not working - so I assume, You need help with input parameters or server configuration (permissions for example) to execute the script. So - if You decide that I could help you, please tell more (or send a screenshot) what seems to be blocking script from execution.
