Targeted Facebook Fans

I need to promote a concert/band in the northwest USA on facebook. I am looking for proposals to market the event and band page to a large number of people within my city. Please be specific with your plan! About how you can raise awareness about an event and get people to "like" a given band. We are new to facebook marketing so the more detailed plan the better. I think we need people from the city to "like" the band. There are already a lot of people who like the band in the city, but they haven't used their facebook page to market and find those likes. Thanks.
