@TFuhrer if you want actual direct advertiser and not another broker, ask them for offer owner details, billing terms, and if they can approve landers internally. Most “direct” CC submit guys on forums are just 1 hop closer to the source lol.
Also mention your geo + traffic source when asking, otherwise serious advertisers wont bother. For sweeps/CC submit they usually care a lot about cap, scrub rate, and chargebacks, not just “I can send traffic”. Had this same issue before, got better replies only after showing 2-3 days stats from a network offer first.
