Compile list of email addresses

Using [login to view URL] I require a list of email addresses for Malls containing 50 or more stores. The email addresses need to be of either general managers, marketing managers or leasing agents (at least 4 email addresses per mall). This needs to be done for the following cities LA, Houston, New York, Chicago, Dallas, Phoenix, Philadelphia, San Antonio and San Diego . This needs to be put on an excel spreadsheet by city with name of the mall, number of stores and email addresses. Thank you
