Odesk are a large freelance and outsourcing site. You'll be able to find anything from writing and translation jobs to web development, networking and marketing. More than 350,000 businesses are engaging on Odesk making it effortless to line up a project to earn a couple of dollars with. I had found that there are enough tasks for almost all the categories that you can possibly think of.
They offer two types of jobs; hourly and fixed price. With fixed price you'll have no guarantee of payment, wherewithal hourly rates you will get more priority and guaranteed payments for the hours are tracked by the Odesk team. There are no membership fees, only the site takes a 10% fee for what you're paid, for instance you will get paid a $40 and they will deduct $4 which is very reasonable in my opinion.
Face it in the long run it takes money to make money, and the little bits here and there working on freelance sites really adds up in the end to get you online freedom in a big way. Working online takes time to perfect and to get scam smart, if you fail just try again you'll get there with patience and a bit of hard work.
