Email scraper from google search results

I am looking for an email scraper that does the following: 1. Accepts my keyword/search string and runs a google search 2. Goes through every search result (google displays 1000 total), scrapes the site, and records all emails that match the domain suffix. (on domain [login to view URL], support@[login to view URL] is recorded, tracy@[login to view URL] is rejected) 3. A fail-safe mechanism should be present in order to restart a search at the point of an unexpected error. 4. I should assign the name and location of the output file (.csv format). Output file fields: root domain, email 1, email 2, email 3, etc. Cap emails collect at 20 per site to avoid additional problems.
