Bridging between the web and the real world

In a world of 7000,000,000, in a country of 60,000,000 in a town of 30,000 people, how do you find 100 clients for your new accountancy business?
Why you search the 7 billion of course via the internet until you find some who happen to be near you and need an accountant, or at least like you enough to pay you anyhow. OK got that thanks.
