About a month ago I posted an ad on the local craigslist service boards. Totally forgot about the thing until Saturday, when a prospective client called and referenced the ad.
This client needed SEO, and they needed it done fast. I sent a full proposal his way Sunday afternoon, and now it's late Monday, and I've got a new client.
It just goes to show that there are leads to be found everywhere, and to keep at this "offline thing" because if there's a marketing method that's closer to printing my own money, I haven't found it.
