As others have said, really nice design. I know a little bit about this market (business courses/internet marketing gurus) so here are my thoughts/questions:
1. Are you creating the content yourself? Are you partnering with domain experts?
2. Are you targeting corporations or individuals? Corporations likely have their in house training tools. For individuals and small business owners, "Learning is a competitive advantage" is a very weak message. Most people who would want to buy from you want to know how to get more traffic, how to get cheaper traffic or how to make more money from the leads they get.
You are competing with serious hustlers like Frank Kern and Perry Belcher, both of whom are extremely aggressive at what they do (they've had issues with the FTC) and also extremely successful.
Having hung out in both worlds, here is common issue I see. The HN crowd is generally very bright and talented. They have great design insticts, coding skills and a healthy dose of "do no evil" sensibilities. But they are too soft-core to make money online.
The hardcore internet marketing crowd (think warrior forum) doesn't care about design or saving the world. They make do with ugly 'geocities era' landing pages. But they sure know how to make money online. I would suggest you spend some time in this latter world. You will learn a thing or two that will help clarify your offering, target customer and value proposition.
