Does anybody offer their services on Upwork, Fiverr, or a similar site? I am thinking about doing so to try and generate some extra income as a freelance writer, editor, and proofreader.
The problem is that both websites have many poor reviews. Many sellers complain that buyers want constant revisions and additional work or they will leave a poor review. The websites also have very high fees. Fiverr charges 20% of every transaction. Upwork also charges 20% of the first $500, but less as more work is billed. Fiverr is also located overseas in Israel. Freelancer requires sellers to download and use a desktop app to track hours and work completed.
I legitimately believe that you would do a fine job there, but you have people overseas (some masquerading as being domestic) willing to do the work cor pennies on the dollar. People still use their wallets.
In my opinion unless you are ULTRA specialized in a needy field there is no way to make consistent supplemental income.
