It is important for you to identify the specific market segment you want to serve; avoid targeting everyone. Also, when marketing your services out there, tell your audience exactly the problem you will solve for them, i.e the outcome. Reach out to the people within your network, maybe those you have interacted with in whatever capacity. If you are active on social media for example, you can post content on your pages to encourage engagements first, then eventually introduce your services. Once you get the first client, ask them to give honest reviews about your services. This will be your pathway to getting your subsequent clients.
