Odesk

Odesk is one of my favorite sites for freelancers.  I know there's Guru, a similar site.  However, I like the insurance plans at Odesk.  There's something about being able to get into a group insurance plan that this freelancer likes.  Don't let the online environment scare you.  Yes, you have to interview for some of the jobs.  But, there's a job tracker, money is paid in advance to Odesk for certain jobs, there's a time tracker utility to make sure that you get paid (or that your contractor is working).  It's great for writers, designers, developers, editors, etc.  If you've ever wanted to be a virtual assistant, you can give it a try here too.
