Get REAL App Installs (Android) - App Promotion

Hi.
I have This App: https://play.google.com/store/apps/details?id=com.polinome.polinome
I am needing Installs for it (REAL Ones).
How many REAL Installs can you provide me at what price?.
Or what would be The CPI?.
Or, whatever 'Your Installs System / Budget' would be.
Send me a message if you are interested.
Thank you.

Damian.
