Be a freelancer
Freelance work are very good for a side job that you can do on your spare time.
They have many online jobs, like data entering, web creating etc.
These are the comparison of the top freelance sites.
Upwork is the largest freelancer site in the world. This is the best place you want to be if you're looking to start your freelance work. They take 20% of what you make, but it is definitely worth it. There are 12M freelancers, 5M clients, and 3M jobs posted annually. If you can't find jobs here, you can't find them anywhere. You can get 20 connects a month for a base plan, 70 for a plus plan. 2 - 6 connects are needed to bid for a project. 1 connect will cost you $0.15. The base plan is for free, and you get 10 connects each month. When you get more jobs, you automatically get more invitations that don't use any connects. Rather, Upwork gives you 10 connects as a reward if you reply to an invitation.
They will give you an instant $20 if you apply from the left link. 30M freelancers, and many designers, developers, and writers.
They don't have a free tryout. You have to pay to get connections. They say that you can discover flexible jobs that are far better than a typical job. FlexJobs makes it easier, faster, and safer to find a job that better fits your life!
They don't have a free trial either. $2 for 30day trial period. Then $19/month. They are good because they send you a list of jobs that you have interest. It is always a hassle if you need to go look for the best opportunity and of course there are already many candidates that are bidding lower than you. It really takes time to search for one, but if they do it for you, it is much easier.
Fiverr has a different approach than rest of the freelance sites. The ones that are posted are not the customer. It is the freelancer who promotes their ability and the customer picks and choose from different people. Interesting but probably hard to get a job for a freelancer.
