I started doing volunteer work for charities, and my local community. After a while, word of mouth led to paid jobs. Also, whilst honing my skills, and taking part in communities like Dribbble and Forrst, I had other job offers. One of the more significant offers I have had recently actually came due to my blog (where I write about web stuff, mainly CSS). Lastly, I have had people approach me after seeing some of the crazy CSS experiments that I love to do.
