I am developing a site on a local server, it is not yet ready for the hosting.

I want to change a lot. Also looking for the option of replacing Google maps Yandex maps, because in Russia the exact location only Yandex maps.

Hi,
I haven't heard about Yandex map, so i don't know how to replace Google map by Yandex map. I am sorry because we can't help you in this case.
You can develop that function, and if you have any question about Google map, i am happy to answer you.
Hope you can understand
