I love the idea. I've considered this idea many times.

In terms of execution: the formfields should be on top of the page. Put the "your email" field at the bottom. You want people to start thinking about what to enter in those fields. You need to put less text on the homepage, or lay it out better visually so it doesn't feel so much as a wall of text.

For SEO: you could start publishing recommendations/tips (after they were paid for) on aggregated pages too, to get people to link to those, and to show what your value is before people actually use you.
