Video Game Publisher

I have created an android game with Unity3D and I am looking for someone that knows his way around publishing, publicising and so on. The game is on Google Play but I cant seem to be able to get people playing it except for a few of my friends :-)

Let me know what the cost would be to help me out and make sure I can make some money making video games. I currently have another game in creation that will need the same thing soon.
