I want to promote my android app

I need a person who can do Mobile App Marketing for me. I have made a game in android studio, and not have uploaded it on playstore as of now. I have montized the apk and it is showing ads.I want to market this app, I have hosted it on github and has also made a website from which one can easily download the apk and install it in his/her smartphone. Through my Google Admob account I have the access to know how much devices are currently having my apk. I want a few thousand installs. For this I want someone who can market my apk.
