Perhaps you have your own website already. This next idea may sound simple, but it’s something that could have a great result for you. Do you have email addresses for your current clients and customers? Have you told them about your new website? Sometimes people need reminders, and a little incentive to suggest/refer your website to their friends.
Send them a letter to tell them to check out your website (give them the link), and tell them it is very much appreciated if they would let their friends know about your services as well. You could also offer a referral fee or discount on their next purchase if they refer a new client.
