The same way you turn anything into a business: figure out who will pay how much money for what. Then, figure out how much it will cost you to provide that to them and tell your future customers that you exist. If the former is more than the latter, you might be able to make a viable business.
Your existing users might be good leads, or they might not. At the least they see enough value in your offering to use it for free. Talk to them and find out what they think you’re adding, and figure out if that’s something people might pay for.
