@whiteplane - In most cases you will have to go out and find your own work. That is why it is so important for any freelancer to have a good website which is simple, easy to navigate, and makes their work look fantastic.
Any prospective client should be able to go to your site, see exactly what you can do, get a sense for your rates and find out exactly how to contact you. This is the 21st century. Anyone who does not have a good website is just shooting themselves in the foot.
