I work online a lot while not teaching. It is a good way to use those hours in the mornings when you don't have classes yet but can't exactly go out and do anything. I wouldn't say you really need web skills to get into it, If you know how to write a post on this thread or email your mom to say you are fine in Taiwan, you can handle writing a website.
There are some decent resources out there that I used before to learn the ropes and build my first sites, so if it was something you were seriously considering you could do it. this one
is free for people to join up and learn about online business. They basically have a training program and some free hosting. Obviously they want people to join up for the premium service which is how they make their money, but you could learn the basics and get 2 websites with them for free.
p.s. I went on to subscribe to premium for them and love it, so I am biased, but it isn't going to cost you anything to investigate.
