Which is a good network to join to promote app installs as an affiliate?

I have experience doing installs for desktop apps and want to move into mobile. Anyone know where I should begin as an affiliate?

Thanks in advance!

Appflood, yeahmobi, brushmedia and many others are there. But I see high paying offers for direct apk or zip files. For play store apps the ecpm is less than what we would pay ad networks for installs. Any strategy to select offers and bring installs/actions to the offers?

How do I get my hands on the direct apk or zip file offers? My strategy is paid search.
