Looking for XML ppc ad feed referral

[anio]

Hello,

We are looking for an XML ad feed to monetize our portfolio of content and portal sites in different verticals. Current portfolio (and growing) averages over 500k uniques a month. Looking for a premium XML ad feed as alternatives to restrictive ad display options of adsense and current premium ad feed (which only offers javascript for ad access).

Would appreciate some help in a solid company that anyone is currently a publishing partner of. More than willing to sign up under you to earn you referral %'s.

PM me any leads or suggestions. Thank you very much.

Sincerely,
Anio
