influencer for coloring books

We are looking for an Instagram influencer to help us promote our coloring books. Our target audience includes both children and adults, so we need an influencer who can speak to both of these groups. The primary goal of the campaign is to generate conversions, so we would like someone who can focus on promoting our product and persuading followers to purchase it. We would also prefer someone with a creative eye who can think of new and innovative ways to market our products.
