@monkee - its probably easier just doing some research online, a lot of the stuff is ever changing and a lot of the basics can be picked up pretty quickly and generally there's a lot of charlatans in the social media industry
I don't think there is a need to join any social media course..
Social media is not a complicated subject.. You can learn it on your own..
You just need to search some tutorials, preferably videos that are uploaded by experts.
Unless you want a career change or have a lack of work, I'd find someone who is does it for a living to partner with and outsource it. It can suck up a lot of time - especially if the client wants to know ROI.
