For a freelancer in today’s marketplace, Upwork is certainly one of the most well-known. When the two leading platforms of freelance work of yesteryear, oDesk and Elance, merged, they created a behemoth of 12 million freelancers and 5 million clients listing upwards of 3 million remote jobs each year. Almost every freelance niche imaginable exists on this site, but be warned: Upwork takes a 20% cut until you build up a regular relationship with a client. So while you won’t earn as much from the remote gigs you may find in a carefully curated marketplace, you will have ample opportunity to develop your chops, if you happen to be a beginner.
