Ask HN: How does a displaced IT professional get started in the software world?

I've worked as an IT professional in my state schools for over 8 years now. In my job capacity, I've covered the gamut of IT related disciplines from desktop/server/network service and management, to software development/deployment. In the last few years, I've transitioned to more of a web developer as service needs were identified and providers were few and far between. I like doing this work and I'd like to continue to grow... the problem is, I live in West Virginia with no immediate plans (family reasons) of leaving. Opportunity isn't exactly within reach here.

So, I started looking at remote opportunities... and I've hit a wall. My jack-of-all trades resume isn't fitting for this sort of work, so I need to start training towards a more refined skill set that is more sell-able. I don't know where to start.

I currently work in PHP/JS/MySQL, I'm comfortable in Java/C#, and have a passing knowledge of many other languages and frameworks. If you were going to start over, right now, what would you be learning?
