SharePoint Site Users & Hits Count Report for the past 30 days

Another SharePoint Report Requirement: Need count of users & hits on each site (not for site collection - site collection has OOTB report! but at site level) for a particular web application for past 30 days!

No worries! My code goes here:

Find Hits Count for the Past 30 Days:
