Need Help With Item-Based Trigger

I want to set a trigger that is based upon the destruction of an item that is just laying around on the map. Sort of a reward system for breaking things. How do I go about it? I've totally hit a wall with the trigger system.

Any advice? I know this probably isnt a simple fix, but there has to be some way to get it done...

Something like hero/unit kills unit
if killed unit equal to [item] then add 10 gold to player 1

Thanks for your response, Milkman.

Are items treated as units in an Event? I thought there was a distinction of some sort?
