Which of the following do you find most interesting and would potentially invest money in ASSUMING that it's done well and I teach it personally to a small group?   Email list growth coaching. From ground zero all the way through having a nice size email list of your own. Live coaching with a small class. I'm too new to know what I want. I'm willing to take coaching though if you can help me start making money!

Write a book! A course taught live by me with a small group. We'd start by researching a good subject and work all the way through getting it up for sale on Amazon.com. I'd be working with you and we'd push you to get it done. Learning to work with local businesses as an Internet Marketing consultant. Live coaching with Andrew and I (the founders of OfflineBiz.com). We'd push you to get a client and start making money.
