Professional Webinar Training at a nominal fee?!

Hi all, I've been looking around for on-line training webinars of professional quality, the closest that I've found are sites such as Parleys.com - but they aren't really training sessions per say. That has made me start to wonder whether there is a market for me to do my own professional webinars at a nominal fee - say £10 per session! My goal would be to set a price that permits individuals to purchase training sessions, simply by reducing the cost to the minimum but increasing the number of people in the webcast. I've had the luxury of being to Learning-Tree courses, costing my employer £3,000+. As an individual, I would love to go again, but alas my employer is not likely to send me any time soon, I also personally don't have that sort of money to spend! I would love to hear your thoughts, in particular it would be great if you could spend some time completing this quick survey? I do appreciate that you might want to just reply here instead, either way, your feedback would be very much appreciated. Regards, Rob - SpikyOrange.
