Dear Employer,
I would like to help you improve your level of English. I am fluent in English, and have graduated in Law degree from University of Newcastle, England. My spoken English is on a very high level, even better than some of the native speakers, as I don't have any strong accent (or so I have been told!). I will help you improve by showing you when you make mistakes, and help you correct them, so you yourself with find a correct path, rather than just giving you an answer. Also, we can work on different topics. I have helped improve my friend's English this way. I am very professional, polite and easy to work with.
Also, I would suggest to hold conversations over Skype (although that is optional), and to have a test conversation prior to final agreement. It must also be noted that currently I am in Belarus.
I look forward to hearing from you!
Kind regards,
Alexandra
