Social media freelancers tend to be in the B2C space which, I suspect, is very different from the experience as a B2B freelancer, which sounds like what you were doing. I came down the management consulting freelancer route too and I feel for you. I know how hard it can be, especially since in most cases you’ll end up several levels removed from the end client and have to endure being nickel and dimed by the people further up the food chain.
