One of the best ways for small business professionals to get clients is by referral. However, the process of building sufficient word of mouth referrals can seem daunting. Many referrals come from your existing clients and people who already know you, but that's a fairly limited number. The next step is to drum up new business referrals from people outside your current network. A better question is how to increase your network to include more people. In order to refer you business, people need to know you, like you, and most of all trust you. They want to be assured you will take good care of the clients and friends they refer to you.
