Import or Export a google map

Hello, I'm looking for someone with expertise to help me import or export a google map. Someone has shared a URL of a map that has 700+ locations. I can see it in my own google map but it doesn't display correctly. So I need to work around this somehow. Maybe export the map so I can then import it. Anything, as long as I can see all the content of the map, even in google earth would do.

Thanks

Will pay $12
