Gather Business names and Emails from directory website.

We need someone who can gather the business names and email from a directory website.
The website link is http://www.4ni.co.uk/northern-ireland-directory.aspx

We would like a quote for extracting emails from all categories but if this is too large a job then one category at a time.

We need both the Business Name and Email
To make sure no fake emails are added a random test will be done on a few emails to see if they actually exist and match the directory.

Please provide your quotes.
