Hi there,
Well, there are so many ways to try to bring in more attention to your business. You can try Facebook, as others mentioned, you can use Twitter (which also means you need to get followers), you can join email lists to gain a 'downline', which could take months, you can post ads at classified ad sites, and so on. It can be very frustrating, I know, I'm doing it myself

I have a free ad share type newsletter where you can post a free ad in it... it only allows 10 ads at a time so at least you're not competiting with thousands of the same types of ads. If you're interested you can check it out. To me, the more exposure the better, especially the free stuff
Good luck!
