My three big projects (dbinbox.com, textbooksplease.com, and emailtipbot.com) cost almost nothing out of pocket to get off the ground sans about a week of my coding time, ~$8/month in server costs, and ~$10/year for the domain name. Any money they've made gets immediately reinvested in advertising. One of these days I'm going to make enough to pay myself.
