Programmer - Data Scraper

We need to scrape the informations from the businesses on those 3 websites.

http://www.wififreespot.com/
http://www.hotspot-locations.com/
http://www.openwifispots.com/

As you will see there are several hundred of thousands of leads.
We need name of business, address, website url, e-mail, phone number
How would you proceed?

Thank you,
