I work with this exchange as a client. It was founded by the well-known webmaster Alexey Sorokin. It seems that it was initially created for his own needs and then opened up to everyone. As a result, the exchange is mainly aimed at webmasters who order texts for informational websites. I assume there are no orders for commercial texts like "installation of plastic windows" or "purchase of a tracked tractor" here. For copywriters, this is rather a positive aspect, as the tasks are more creative. As for prices, WorkHard can be compared to fast food in the world of content. Everything is set up for mass work. It's cheap for clients, but it doesn't provide significant income for copywriters. On the other hand, there are maximally standardized technical assignments and minimal communication between the client and the performer. Overall, I recommend this exchange and often order texts here myself.
