I am trying to complile a list of contact emails for bars in the United States. I need a spider that can crawl the web and find these contact emails.
One idea is for the spider to start at citysearch and then look for listings that have their own sites linked to the listing. Once it finds the personal bar sites, then it shouldn't be to hard to find the contact email. I then need the contact email, bar name, and location (address, city, state) to be put into either an excel file or some other type of file.
This is just one idea I had for how the spider can work. However I would like the spider to be able to start from other places as well so I can obtain as many contacts as possible.
If you already have something built that you can customize, that is fine. Or if you want to start with something open source, thats fine too.
