Have you ever thought about networking on the social networks? Alot of businesses are now going to that to find vendors. I use MerchantCircle. Check it out. You build your own profile and connect with local businesses. Its just like word of mouth but online.

Also I use a service that actually provides you with local leads for customers that are looking for your service. Its reasonable and a great way to get yourself established without having to spend too much time advertising.

I have a home improvement business and know how hard it is to connect with clients. I hope this works out for you.

Good luck
