If you are referencing the blog post, $50 was the charge to the client and I received $40 after the 20% Upwork fee.
It was about 1,500 words with no rewrites - the client was happy with my content. The topic was something I am very familiar with, so it was an easy, quick write-up for me. I have been careful not to bite off more than I can chew while I am starting.
I do plan on raising my rates once I get some more jobs under my belt.
