Social Media Management for a Gaming App and Community

We are a gaming app and want to have a greater presence via social media -- particularly on Facbook, Instagram, Pinterest and Twitter. We are currently Australia-based, so want to target Australians only for now (we will be expanding next year). You must have: - excellent English skills - expert knowledge of Facebook, Instagram, etc; including plugins and social media management tools Please do not apply unless you meet these qualifications. We currently have Facebook and Twitter accounts. We post every day to Facebook, but we want to use a server such as [login to view URL] that automatically posts to Instagram, Pinterest, Twitter, Tumbler etc as well. Note: [login to view URL] is not accepting our facebook channel. We're not sure why, but there seems to a bug. If it can't be fixed, maybe there's another service we can use that makes it easy to post to all social media with one post. (We'd need advice how best to do this). We see this as a small job to begin with, and if it goes well we can expand it. The goal of our social media presence is to: - increase downloads of our app. - allow us to easily and effectively communicate with the players of our game (our community); so we'd like to see an increase in comments, likes, retweets, etc.
