collect emails from yellow pages

Hi I bought the chrome extension email extractor and I wanted to build a list of email addresses of " attorneys in madrid" who are listed on www. paginasamarillas .es which is the spanish version of " yellowpage. com " using the chrome extension email extractor.

In the guide it says:

We suggest this recipe to collect email addresses with Email Extractor.
Feel free to adapt the recipes

Recipe Number 2

Build a list of email addresses of " plumbers in Los Angeles " who are listed on
" yellowpage . com "

Step 1 : open this URL
www. google. com/search?num=100&pws=0&q=los+angeles+plumber+site%3Ayellowpages.com&oq
=los+angeles+plumber+site%3Ayellowpages . com

My 2 Questions are:

1) can I build a list of email addresses with www .paginasamarillas . es/

2) I guess I would have to edit the url on step 1, what would be the url I would have to use in my case? if I want to build a list of emails of "abogados en Madrid" and for the other cities in Spain?

www.google.com/search?num=100&pws=0&q=madrid+abogado+site%3Apaginasamarillas.es&oq
=madrid+abogado+site%3Apaginasamarillas.es

Would be this the right url?

Since you bought the product why won't you just send them an email instead?

Or Google YouTube for video guides. That's more direct for help don't you think.
