Are you looking to serve more people vs 1-1? If so webinars are a great format. In fact I think that often times group learning can be more powerful as many ask questions that others have but don't realize they had. So the learning is often times a greater experience in a group fashion.

What steps to take? Market to your audience your service and how it will be conducted via a webinar. Your fee for this type of training should be considerably lower and therefore appeal to your client base.

Hope that helps.
