You must put yourself in front of the buying public and that means mingling with people at social events or conferences joining a meet-up event posting on social media consistently and interacting with people as much as possible. This is what networking is all about and allows you to expand into other areas or categories that you may have never thought about. You may meet someone who can offer assistance or experience in an area that you would like to expand on in the future. You never know where networking will lead!
