What Internet Marketing Course Should I Take?

Hello, I have started a self-proclaimed business that currently specializes in Mobile Marketing, thanks to Mobile Monopoly by Adam Horwitz and I am about to start setting up some campaigns, but I have a problem. The company was originally meant to be a Mobile Marketing only company, but it is called Ellis Digital Marketing. It was called Ellis Mobile Marketing, but I changed it as I want to be bimarketarey(Made up word, sorry), or handling marketing in 2 different ways, so while Mobile Marketing will always be my specialty and primary focus, I also need to start an Online Sector of my business. I know of many courses(To name a few, Lee McIntyre and the Platinum Program, Philip Mansour and Confidential Conversions, Desmond Ong and Niche Funnel System) and I only want to use one system for my online business. At first I thought I could just run several businesses, and have each business utilize a different method taught by a different course, but that would take up too much time and ysis. So I want to only use one, and I want to hear from someone who has used the teaching of either: Lee McIntyre, Philip Mansour, Desmond Ong, or Adam Horwitz. Thank you.
