A friend of mine, Cory Miller, who I met while at Midwestern Seminary, has a ministry working with churches and ministries, helping them to streamline their communications efforts. When I met Cory he was the head of communications for Midwestern and he continues to do a fantastic job in this area.
Cory has a website for his ministry that I would recommend you take advantage of. He offers a tremendous amount of free resources online that may serve to be helpful to you. Check out churchcommunicationspro.com!
