Hi! We created a DIY service that helps developers market their app on social media

Hey! We help developers get more exposure to a targeted social media audience through influencers (social media accounts that have influence over a large but targeted audience) to get you an initial boost in the Play Store. We have a flat rate of $3/1000 followers that the influencer has, starting from $75 for someone with 25,000 followers. You have complete freedom to choose who you want to promote your app and what you want them to say/when to post it etc. and you get to communicate directly with them. We just wanted to see what you guys thought about the usability and layout so we can make it better for you. Thanks!
