From 0 to 30 subscribers in how many days???

So I've challenged myself this morning by seeing how many people I can get to sign up for tutorials on using Drupal+Paypal+My Brains. Those are the three ingredients I've got in regards to developing an online course where I show you how to use Drupal+Paypal+Your Brains to sell services online. So the details of the course I am offering as as follows:

1. Learn to use Drupal
2. Find out how to setup Paypal
3. Format your brain (knowledge base) so that people will purchase what you know.
