Aaron Wall of Seobook.com fame is giving away free consulting - normally worth over $500 / hr! He'll give you an idea that will make good money within 3 months.
The best part, it's a really simple plan - anyone can do it. I can't believe he's doing this for free!
Here's a sample from an IM chat with him:
AW: you market THAT angle. no i am saying right now, put another way, i could work 1 hour a day developing the blog idea i gave you and i would bet inside of three months it would make far more than your idea, so listen to the idea and run with it...
The only problem is that you have to read a long blog entry to qualify for this free advice. However, I guarantee it's worth your time.
