That's a great goal! My monthly membership programs generate a lot of revenue from relatively small amounts of incremental effort.
In fact, I'm successfully selling a program like this right now (http://TrustedAdvisorCommunity.com). I've developed a particular series of emails that I send to people I think are right for the program. Some of them agree to sit down with me or discuss it further over the phone. Most of them end up signing up.
Bonus tip: You won't get anywhere selling it as an "infoproduct/coaching continuity program." If you want to clarify what you're selling and why people would want to join and turn that into a compelling title for your program, plus get access to my email templates, feel free to set up a call with me.
Schedule a free webinar and offer a value sample. During that webinar continue to reference the benefits of your monthly program. Make a call to action at the end of the webinar, inviting your audience to continue the conversation.
