That's also my recommendation.

You might also want to get involved with your local chamber of commerce. They probably have events and meet+greet for local businesses. If you have a local small business center (that handles things like registering companies and company names) they may also have events for local business people.

I suspect you'd probably get at least a little bit of traction from some slimy moves like putting up flyers on intersection sign posts and community mailboxes and other public places, but I don't recommend it. Again, it's slimy.

Word of mouth is by far the best way to get solid leads. Your clients will be your best sales people if you have pleased them. Much more effective than any ad, regardless how glossy.

But do get your site to the level you want - it will never hurt.
