Police Officer Hopeful

Hey guys I'm brand new to the site.  I am a senior at Charleston Southern University with a Business major and Religion minor.  I also am a senior captian there on the baseball team.  I really have a passion to become an officer around here when I gradate.  I would like to apply to City of Charleston, Charleston County, Dorchester County, North Charleston, and Summerville.  Also I have done multiple ride-alongs with North Charleston and Dorchester County.  Can anyone give me some advice about getting hired, or any resources you'd like to share any help would be great thanks.
