I run a performance-based ad agency and I specialize in helping people increase their revenues with highly-targeted advertisements that you can add to your site and/or to the emails you send to your opt-in list.
Typically your revenues will be much greater than PPC revenues. You receive a much larger piece of the pie historically.
I don't get paid if I can't help you increase your revenues - so it's all on me. And I can help you do this in a way that won't affect your current sales, so you risk nothing.
