Hi, mbasiuk.
I would highly recommend talking to Dzmitry about doing a course (or at least a presentation) for your company on PowerShell. He is also in Kiev.
I don't know him but he has presented on PowerShell in the past and is an MCT.
He also has a blog that includes PowerShell content.

He mentions a presentation he did in 2012 here:

I hope he doesn't mind that I mentioned him. :)
Good luck!
Best wishes, Davin Mickelson
