Ask HN: Which ways of finding new clients works for you?

Hi HN!

I've recently started a web design business, had a couple of friend/family pro bono clients, and now need to get some real ones (and real money).

Word of mouth will hopefully eventually lead to regular clients, but that requires an initial set of clients.

What methods have worked best for you?

Specifically, which of these have worked to get you clients?

* AdWords?

* Leaflet drops?

* Networking meetups?

* Cold calling?

* Going door to door?

Any others I've missed?

Cheers
