We have some powerpoint maps (
http://www.flashimap.com/powerpoint-map.php) and offer customization, but it would be very hard for you assign settings to each region/ county due to the amount.
You may consider to use our map software, to publish static map image (e.g. heat map) and import the image to your Powerpoint.
Please download a free trial version to test if it suits your needs first:
