I just like to torture myself with all of the work I seem to put on myself, but I signed up today for oDesk. I had been checking them out for several weeks and finally decided that I might as well build up a freelancing business. To tell you the truth I am a little bit concerned about my work at home job with West at Home. Though everything is fine right now, you never know when the company I am assigned to might pull their account and I would hate to be out of work.
So I decided to give oDesk a try. They seem like a very organized and professional company. I did a lot of research and found that if you do certain things like make a really good profile page and test for your skills (they provide free testing) it helps in getting hired for jobs. The advice I read said to start with a job that is really simple, even if it doesn't pay much, and that will be your first feedback so that you will get better paying jobs to slowly build up your freelance business.
So, as I find the time, I will start doing my testing and see how it goes. If you think this is something you might want to try you can read about it and sign up. You can be located in any country.
