Hey Andrew, what about letting those videos be free, and selling DVDs per months, peoples can watch the content online for free (advertising support) in this way you keep growing and peoples willing to pay can order videos on a dvd, let's say each interview on a dvd cost 5 $. Next option, you can aggregate videos of each month as dvd and sell them for ~9,99 $ , and the next alternative will be to create an ebook from the transcripts of each month videos and sell it for a couple or dollars, you can organise this in topic (ebook transcript for freemium Business model, ebook for videos plattform entrepreneurs.....you can combine it as you want: we call in in mechanical eng variants)... That's my 2 cents. Some peoples may pay the 25 $ , but most of your users won't, if you want to go with the subscription , what about 1,99 $ /months * many users and steady grow?
