As a proof of concept, I whipped up something that might help you.
Input your search query (ideally you will use filters to avoid having millions of results) and you will be shown results directly from Google.
Page title, url and snippet are automatically retrieved.
There is also an export button that will place all the URLs in a new email message (not sure which elements you're interested in exporting).

hope it helps,
