lead generation & increase social media following

I launched a faith based (christian) worship music school and I need to work on my branding, lead generation and social media following so that I may have increased exposure when enrollment season happens for my school , three times a year. This may look like a social media, google listing ads and anything that will get people to call us more! We currently have about 80-90 students and we are launching a semester in january again. It would be great to establish a strategy by then.
