Copy business 815 addresses and phone numbers from a website into a spreadsheet

We wish to create an address spreadsheet with all the data on this page:

http://www.gundealer.net/pages/home/search.php?action=&county=&pg=*

The spreadsheet needs to have:
- Business name
- Postal address (a column for each address line: Address1, Address2, Address3, Address4, Postcode)
- Telephone number

There are 815 shops on the page in total.

Preferably, the work will be complete by Monday 29th August.

Thanks for your interest!
