Getting the Word Out?

How do you get the word out about your church: Yellow Pages, newspaper, direct mail, door-to-door, street preaching, block-party, service projects? Most churches want their communities to know they exist and get a certain impression of them. We covered some of this in Basic Training and the Nehemiah Project of the SBC, but I want to hear from you guys and hopefully get some new ideas. My question more specifically is, What are some good ideas for getting the word out about your church on the cheap?
