I was struggling to sell my program to more than one person although several students had expressed interest. I held a webinar on the basic principles of dissertation and proposal writing and at the I showed them a slide with my product and bonuses they could get if they signed up before midnight on 31st January. I left the QR code on the screen while I went to Q&A. By the time we finished the webinar 2 more people had signed up. Just before midnight on 31st Jan, 2 additional people had signed up!
