create interactive google map

I would like to add an interactive google map page on my website, similar to following: [][1]<[login to view URL]> OR <[login to view URL]> You will be provided with about 100 street address'es to include, and on the map I would like the general location shown (so viewer has a good idea where it is at) but don't want the exact address listed. Also, each of the properties has its own webpage listing on my site, and would like a link to its location on map from the page.
