Webscraper yell.com

Must have
I would like a python script that will enable me to pull company name, website, email and phone number from yell.com.
I would like to be able to edit the script to select the industry and location.
The script would populate a csv file that I can then use.

Nice to have
To be asked for the industry and location at run time.
To be able to pull multiple pages at once.
Using comments, so that I am able to navigate the code so that I may be able to change the site and tag selectors.

I have some python programming experience and comfortable configuring libraries and IDE's.
