Freelancers.com is one of the best website for online freelancing work. Almost 20 million  freelancer work on this site. I am working on this site last 2 years. You can earn money to work from home without bonding in any time frame. There are two types if project here. one is biding and another is on contest based. You can go with as per you interest.

I mostly participate in contest based project. In this project we have to send Design as per brief before payment or selection. This is a little risky but I love it. For freelancing Work there are many graphic design contest website like 99design.com, designcrowd.com, designcontest.com, crowdspring, fiver, upwork, peopleperhour etc.

You can check my another video on how to win logo design contest. Link given in description.
You can create account free but for fully activated account you need an ID proof. You have to upload it with a photo with a unique code that provided by Freelancer.com.

You will get paid after winning or completion on project by PayPal or direct Account with 10% deduction, that is freelancer.com fee.

In short, I can say that for making money on online platform for graphic designer keep some key points; original, unique and creative.

Less is more.
Thanks
