Ad Netork with good support recommendation

Hi all

I’m wondering if someone could recommend an ad network to me.

It must meet the following requirements.

[li]Be Google Compliant
[/li][li]Allow full-screen Interstitials (static and video)
[/li][li]Allow banners
[/li][li]Easy and quick Integration with good and up to date documentation
[/li][li]Allow me to serve ads via it’s network and fall back to AdMob when ad ad isn’t available (again, with quick and easy set-up)
[/li][li]Good and quick support

Would appreciate any suggestions - thanks all!
