OurFreeStuff has a lot of the international offers you want. There's constant email from them with offers expiring, so I'd not expect to promote anything of theirs for long due to the high turnover.
1) EWA will beat any payout you get from any network.
If I have to run marginless, I will. I'm about building long term relationships with publishers rather than making a quick buck. I love competition, get me in a bidding battle with ANY network and I will make them look like shit.
I'm confident I get paid more by the advertiser than any network out there based on the sheer volume we run. More money, more offers, less problems.
