Word of mouth has been one of the most effective marketing tools for me though out the years. IDEA has also provided me some good leads through my profile. I do have a website and it has also worked very well for me because people can go there and get more information about me and my services. Posting on Craigslist is another free way of market your business. Facebook is also great to connect with others, but I still think the best way of marketing your services is by joining networking groups where you can meet people with connections.
