I've been doing web dev on and off for about 2 years not really going all the way with it because I always thought it was going to take years to learn and even start applying to jobs. That's awesome you got hired being so new at it. Your story is a lot like mine in that I too am also working a really dead end job in cust service. I hate it and I've always wanted a job as a web developer.
Web development is not about languages and code - you need to be creative and have an insight into business also - there are too many code jockies who are into 'cool design' and they give their customers the generic cool web site-SEO has to be considered, as in syndicating the website all over the business niche online - in fact you can learn a few frameworks and produce much better sites than these re-inventing the wheel code sites.
