Hi, thank you for buying my icons!
I drew up some coins and wheat (feel free to use them).
I'm not quite sure I understand what you mean about logs - just, in a different style? (I do have a set of wood icons that might cover what you're asking, though they're *very* specific.)
For manpower, do you mean like soldiers? If it's specifically medieval, that might not quite fit this icon set... I'll have to think about what that might look like. I do have a few general population icons somewhere in there, maybe one of those could be adapted...
