1. Get a video testimonial from your client telling others how awesome you are!!!
2. Take that video and share it with your fans and upload it as a paid Facebook ad to disperse to audiences locally in your area.
3. Then go into audiences and review the people who've watched your video, and who've also completed (watched the full video).
4. Retarget "only" those users with an offer to opt in for a consult and learn more about your services.
Inside of Audiences you will be able to find people who have viewed your video and also completed your video.
