It was a pleasure to work on the project. Vladimir will clearly set the task and fully explained the wishes. Payment immediately after approval of the finished work. I highly recommend cooperation)
I was happy to talk in English on Skype with Vladimir, but I didn’t work with him.
Initially, it should be a speaking lesson, and ultimately, Vladimir will need a native speaker.
In addition, I believe that giving an assessment on the principle and on the basis of the previous experience of learning that is unknown to me is incorrect and unprofessional. The word "categorically", as in fact and the tone of communication sounded strange to me, as with students of different levels I have friendly relationships)
After the lesson, a few days later, I had to send a reminder of the payment.
