Interactive maps on a web page

I’d like to put on a map of Taiwan on a web page where one could click to get more detailed information. i.e. they click Taipei and a map of Taipei displays, they click Shih Lin/Neihu/etc., a map of Shih Lin/Neihu/etc. appears. On the local maps (e.g. Shih Lin/Neihu/etc.), I could have an clickable image that would pop up and show more information (like a detailed street map to show landmarks, intersections, phone numbers, e-mails, etc.).

So what exactly are you wanting from us? The maps? Hosting? Tech advice?

You mean something like this?
