All of your threads does have some 'feels' to them. This is the first straight up question and answer thread from your side. But jokes aside.
I own a software development company, purely in the software-as-a-service market. Thus far I have only gotten clients by word of mouth, only recently did I start using social media (fb) and adwords to try and boost sales. But I don't really understand online marketing all that well. For the last 7 years, I only did face to face sales to people that approached me. I did hire a sales person last month, but he will be travelling and setting up face-to-face meetings with actual clients. I would love to get up to speed with online marketing and gather leads.
Going by my need for a marketer or marketing advise, there must certainly be a demand for your skills, especially if you can fine tune it to the current trend of social media and online whatever. Have you considered starting a small business on the side while you study? Doing online marketing, managing Facebook pages and twitter accounts, designing marketing strategies etc. There is even a market for you to manage the content companies place online in order to ensure maximum SEO and advert exposure (look at
