I started my online training business in 2010 soon after I was divorced and I had to start from where I was, with what I had, a PC and the internet. I was teaching in a bricks and mortar business, but this had to be sold as we owned the premises and it needed to get sold as part of the divorce settlement.
I started with an online course delivering the Teaching Qualification that I had been delivering in the classroom, so it was something I already new was in demand, but I was not sure how it would be received as an online course. I started with MOODLE, a free open source Learning Management System, and set up a website to market it.
I had only written the first lesson, as I did not want to write the whole course if it was something that people only wanted as a classroom course. Within days I had sold my first online course! Over time I have, through trial and error, perfected the system and it is the model that I use today.
