Your website is probably the most important part of your business. It is a great idea to scope out the best web designers in your local area. You can do this by searching online for local web designers for your town or city.
Any good designer would be happy to share examples of previous work, and would be willing to allow you to approach past customers to get references. Take a look at their own website too – if they have done a good job for their own site, they can do a good job for you too!
