Design and usability idea for a long list of dealers. Help?

Question

HTML

Hey!
The site lianail.ru has a page with a list of dealers lianail.ru/module/geografia The
question is how to make this list prntscr.com/afkf41 (screen) in accordance with all the laws of usability? It is worth considering that the list can expand up to the villages.
There was an idea to "score" dealers on the Yandex map and use the API to make a search, but the idea died after a survey of the sales department.
I would be grateful for any idea, any useful link to an example or article.

First, select the largest and most important cities and regions
Inside the region - the major cities of this region and a link to all other cities (and villages)
Well, all other cities. If relevant, take a closer look at the numbers, but do not give them any accent. If, on average, there are a couple of offices in one city, then the numbers should not be shown. But by region, for example, show )
