Setting Up Your Sales Funnel
I was thinking of something like this:
1. Create squeeze page
2. Create free report (to give away on squeeze page)
3. Create ebook
4. Create membership site
5. Write emails
6. Set it all up
Then launch through PPC (or whatever traffic method you prefer).
That way you can let it ride (but going back occasionally to add to your membership site or promote a new product to the list) while you focus on your next niche.
