Real estate portal

We need a major real estate portal. The site should have all the functionality of the site: Text hidden. Only the portal should be made not for one country, but for Russia, Belarus, Ukraine, Poland and Kazakhstan. And there should be the possibility of selecting a country, region, city, street from an existing list and the possibility to apply for the addition of all of the above, if one is not on the list. And everything else is an exact copy of the site - an example.
