Influencer marketing is an avenue you may want to explore. Instagram is big with influencers or content creators who recommend services/products that would benefit their group. For example, fashion influencers may have a page on the latest trends, so people who follow them would most likely be into clothing and accessories.
Once you know their audience would benefit from what you are offering, contact the influencer, sell them your vision, and create a win-win-win (win for the influencer, win for you, and win for the customer).
