You could seek out web-design / front-end oriented local consultancies and offer to do their back-end server programming. I would suggest focusing on your current strengths. Doing CS F/T is heavy enough going without having to learn new languages, frameworks, etc. Check out oDesk, eLance, etc. They have a lot of jobs going. If you are disciplined and very productive you might be able to generate some income. The downside being that you are competing with people from lower cost of living countries. If you have server, networking skills then you could look for work with systems integrators who need people to work graveyard shifts in data centres.
