DH started our business in 2005, we started off by all the usual paid advertising, Yellow Pages, Yell, Local newspapers etc.
We have since found though that nothing at all beats having a great service and spread awareness via word of mouth from your satisfied customers.
We also have a Facebook page and a good website with lots of images and descriptions of our work, if you offer a comprehensive site then usually people want to know more about the services that you offer. We also have Yell.com as so many people tend to look online these days.
What are you going to be doing as your business?
