An excerpt from http://www.sitepoint.com/10-reasons-consider-freelancing, by @Craig
I’ve been a freelance web developer for more than eight years. It’s allowed me to write for SitePoint during the past six years and since this is my 1,000th article (cue fireworks and fanfares), I thought it was time to share my experiences of the freelancing world.
Going freelance is a scary step. I dithered for far too long and wish I’d done it years earlier. Perhaps you will too…
If you’re a developer or designer you have a skill relatively few possess. Don’t underestimate your knowledge and talent; others want your expertise. You’re also in a young industry where demand has always outstripped supply. It’s difficult to find good people but, if you’re one of them, you’ll regularly have more work than you can handle.
