Hi patrick008,
my name is Alex Clarke, founder and owner of Oculus Marketing, a PR and marketing firm.
I read your post and we can definitely help you boost your game's ranking in google play.
We can help your app move up the rankings by using our relationships in US, UK and EU media markets that allows us to secure profile enhancing media coverage that puts your app on the radar of potential users. We also can optimise your app store page to ensure that your page feature highly in google play's search results and even run a small ad campaign that increases the awareness of your app which we can convert into users.
However, long term, the best way we can help you is boost your user base. I'm not sure how many users your app has but we can significantly help boost your user base which will at once help move your app up the google play ranking and more importantly, secure income.
Let me know what you think
