Ask HN: How do you market a small consultancy business?

Hey guys

I've started doing consulting with a buddy of mine, doing enterprise software and web development like a lot of the good people on HN.

So far all work has come from our existing network and random introductions and encounters with people.

For a such a small consultancy business do people have much luck with marketing of different types?

Can there be more method to the madness? Something more systematic?

Or is it pretty much always just about the serendipity and happenstance with people you meet at events and through existing friends and customers?

Thanks!
