Many people have made a regular stream of income by freelancing, this basically means that people find work online and complete it to get paid. Once they have finished a project they move onto the next. The best thing about this is the fact you can earn as much or as little as you want depending on the time you have. The safest way of doing this is to firstly start out freelancing in your spare time, make sure that you have a guaranteed flow of money coming in to pay the bills. You can then start to work freelance more and maybe go down to part time so you still have guaranteed money coming in every month. The problem with freelancing is that it's never guaranteed, you have to work hard in finding the work and getting a name for yourself.
After you have done that the work should come to you making it easier but people still have rough patches where people don't need anything doing. To make it easier there are a number of sites where people can list projects they need doing so you and all the other freelancers can bid on the project if you feel confident you can meet the user's requirements. Be sure not to undercharge yourself, take the amount of time and effort that it will take into consideration and charge the client based on that. If you impress a client they will often give you regular work which is why it's vital you put 100% into every project as you never know who's looking at your portfolio. These site often have a reputation meter where people will add comments after you have done their project, this means that the more you do the easier it will become to find new clients as people are often weary about taking new comers on in case they get scammed.
It will be hard in the early stages as you will have no reputation or feedback from previous work, make sure you build a convincing portfolio so that people can see that you are a professional in your chosen field. You can get daily/weekly/monthly reports of jobs that you may be interested in so you never miss out on a potential project. The more you sign up for, the more chance you have of finding work and begin in making serious money in the comfort of your own home.
