Freelancing and starting a business

In my experience, it takes a lot of time to develop the skills and confidence and reputation to be a successful freelancer. Not to say that it can't be done but get a job in the field and freelance on the side.

try upwork, elance and start with friends and family to build a portfolio of work. Build, build, build.

My past experiences with online freelance websites are negative. The payments are low, managing clients is difficult, and competing in price over quality is something that will kill of your career sooner than later.

My advice would be to start looking in your own surroundings for freelancing opportunities. Like Josh mentioned friends and family can be a start. Although if possible try to avoid mixing business with friendships. Instead I would focus on local design & development studios. See if you can get a freelance job with one or two of them. Not only does it enable you to tap into their network, but you get to work fellow professionals. Learning from them is one of the most valuable things in my early freelance career. And most likely it'll get you in contact with clients that would have otherwise not even opened the door for you.

Still, becoming a successful freelancer takes a lot of time, effort and dedication. It's a fulltime commitment. If you only manage to do it during evening hours than it's nothing more than a hobby that makes you some extra money on the side. It's harsh, but it's reality.
