The money is most certainly in the list. If you're at all interested in online marketing, setup email software and create a lead magnet that you can use in your sales funnel. Then, build up that list. It's often said that you can expect to earn about $1 per subscriber per month. If you have a list of 10,000 subscribers, that means you can earn roughly around $10,000 per month. You will need to deliver value and not pitch them on every email, but it is a very achievable goal in a short period.
Sure, there are plenty of businesses offering social media consulting services, but you can stand out from the crowd by focusing primarily on networks that are still gathering steam with businesses. Facebook and Twitter are still the top networks, but businesses tend to struggle the most with more visual platforms like Instagram, Pinterest, Tumblr and Snapchat. All of these platforms have huge audiences, but many businesses don't realize how big they really are, how effective they can be and how to make them work for their niche. Snapchat has more than 158 million users per day, according to Business Insider. Instagram has more than 500 million daily active users, according to Statista, and Pinterest has more than 200 million.

Hands down, there isn't even another platform that comes close.
This has become a popular business model for online entrepreneurs over the past several years, and will probably just continue to grow in popularity.
