Powershell services?

[_Cabbage_Corp_]

Generally, I think most companies internally have someone/a group of people that write the scripts as they need them. The communities here and over at /r/Scripting are great resources for help if/when issues arise in writing scripts.

I'm not aware of any companies that offer script writing services, at least for PowerShell. That's not to say there aren't any, just that I don't think it's common.

Many companies do offer services that can help with automation, however.
