An update on my Upwork job.
Well, it turns out that my US$50 job became a US$100 job. The client had previously stated that if the duration was longer than 40 minutes, he would pay extra so when it turned out to be 66 minutes in length, I asked him if he would be happy to pay an extra $40. He was so happy with the finished product and the communication that he paid me US$100. So, there you go eh ... there are good people out there and even though he still received a highly professional audio file for his project at a ridiculously cheap price, it is my starting point as a newbie to Upwork and hopefully he will leave me a five star review.
Onwards and upwards I say!
