Interactive Geo Map by Regions and Poll System

Hey guys! I would be very thankful if you help with idea I’m working on! I wanna create a wordpress website with Interactive Geo Maps of a country with all regions of the country. I know there are a lot of plugins about that but i want also display mayors by regions. Like when you move the mouse arrow over a certain area and it shows all cities of that area and all current mayors.
Is there some kind of plugin which I can use to do that or I have to hire someone to develop or modify some of the Interactive Geo map plugins?
Then I can integrate a poll system easily so every citizen of a city will be able to vote whether he is satisfied with the mayor or not.
