One thing I have been doing is direct messaging on Facebook.
Think of your client group, for example women in an affluent area (for my client base) then send a few direct messages to them. I picked a well known nightclub fan page in my area and messaged people with price details and links to my Facebook page and found I got quite a few clients doing this with only a few hours work. You also get their friends coming with them.
The snags: some people see it as 'spam' and take issue, but I found most were genuinely interested especially if you are interesting and polite. Another issue is there is a limit to the amount of direct messages you can send each day on Facebook before it tells you off! I think I managed to do about 30-40 a day, just copy and past your message but make sure you personalise the opening with their name...
