Advice for marketing a print newsletter

I'm on Dien's Hidden Business Letters list (and a past paid subscriber too). There are some business ideas in them that I did research on but never implemented (life got in the way). Now I want to turn some of those ideas into a paid newsletter, and offer generic business plans to go with the ideas from my newsletter.

Here's where advice and suggestions are needed, because it's where I'm stuck: How do you market a paid newsletter when no one knows you?

Here's what I came up with after contacting Dien (thank you for suggesting the post here):
1. Classified ads in business opportunity magazines.

2. Articles on business opportunity blogs with link to trial sign-up page.

3. Comments on small/ homebased business sites with link to trial sign-up page.

Have been online since the dinosaurs roamed the earth, so doing my own sites isn't a problem. Also see the "for your email address, I'll send you a free report" shtick being done well for internet marketers. I can put together a freebie sample of a newsletter, but at some point it's going to wear thin with the 'freebie' thing.

Experience: Accountant, community program newsletter editor/publisher/researcher, Bookeeper association newsletter writer/editor.

Inexperience: Copywriting, selling (took me a year to sell one set of pots and pans) and ended with using an auction house to sell items I picked up after reading the Chattel report.

So any help, advice or suggestions would help. Thank you.
