Create patterns for php preg_match

I need someone who is familiar with php preg_match function. I need to create a preg_match for the parts of daily deal websites like Groupon and Livingsocial in cities New York, Toronto, London, Paris (you will be provided the list of websites) - only html elements (not Javascript generated content) - elements like title, price, savings, discount (see detail in attached file) Bid for 10 completed websites. The result should look like attached file output.php. Will be more work to do in the future.
