Are the icons in the attachments the sort of thing you're looking for? I created them using an app called Iconic (
https://play.google.com/store/apps/d...s.iconic&hl=en) on my Android phone. I've attached the icons in all three of the sizes you mentioned.
As far as I can tell the licenses for the icon sets used by the app are all open source or creative commons.
From a quick scan of the icons in the available sets it looks as though there may be two or three more on your list in addition to the two I've attached.
