First, sorry for any bad english.

I was thinking in an mod idea to micro-manage funds of every building. And also, have a factor (calculated by the funds and other opitional factors) that affects the efficiency of the building.

The point is: Except for the API link in the description and an API guide (http://www.skylineswiki.com/Modding_API), I don't know good guides to modding Cities. I do know something of C#.

Could you guys give some good references? Maybe Soda has one sugestion?
