For an instance, I had a college mate who had an amazing skill of coding, being into computer science engineering itself an experience with this field would have graced her certificate, but being in a Gurukul, we never had many opportunities to get out of the campus and apply. Hence, she began her hunt on ‘Internshala’ where after accomplishing one project they gave, she started working as a coder with a startup company and a technical writer, and she got certified for her skills and knowledge while getting paid with an average stipend as well.
I have had some success with Freelancing and Fiverr. What I did was I went to Fiverr and found a service that was selling well, then went to Elance and found someone who did the same thing for less. Then I made a Fiverr ad and sold the service myself. Tiny work once you get it going. I’ve also done the opposite where you go on Elance and look for jobs that you can have someone on Fiverr do for cheaper.
You can pick writing jobs directly from a live job board or have to bid on a job and hope that the job is awarded to you by the relevant client, depending on how the site works. Some sites may require you to take an English grammar and writing test and some may require you to submit a sample or samples of your work while others may require you to take a grammar test to evaluate your skills. If you pass any relevant test, the relevant site will let you take on writing jobs.
