Request for a Suggestion of a Good Ad Network

Greetings,

I have recently made an android app (allows users to download modded games) which already has around 3000 downloads(in just 3 days) with at least 30 active users per 30 mins.
I was able to monetize the app with an ad network called as StartApp but the payout rate is very low. For 3k impressions , 400+ clicks, i got only 0.20$.

Since my app will never be approved on Google Play , i was wondering if there are any ad networks that provide Video ads (or banner ads) and dont need the app I made to be on the market to get approved (for ads).

Thanks,
Cheers

I use Alphagravel to monetize my android app!
