I know you’re smart (you wouldn’t be where you are if you weren’t), so you’ll probably want to check out what your other options are for guidance in this respect. Here are the competitive sites/products I’m aware of. I haven’t used any of them, so can’t speak to quality:
1. Talk at TED (http://www.talkatted.com/)
Jeremy is a previous TEDx speaker. I don’t see any indication of a product or service on his site, but suspect he has one.
NOTE: Twitter account no longer seems active (and the SSL certificate on the site is expired), so I’m not sure if this business is still active.
2. 18 Minutes of Impact (http://www.doloreshirschmann.com/#!18-minutes-of-impact/dgocj)
Dolores is a TEDx organizer. Her 8-week master program is $2,497.
3. How to rock a TED Talk (http://catheyarmillas.com/how-rock-ted-talk-audio-program)
Cathy is a TEDx organizer and has also spoken at a TEDx event. Her audio program (mailed to you on a USB key) is $297
