Hi Ahmed, my name’s David. I’m a British English native speaker (with received, standard, pronunciation—RP) and I’ve been teaching English as a foreign language for over 15 years, to individuals and corporate clients at all levels. I’d be happy to work with you to improve your pronunciation and anything else that needs improving. I’m a full-time freelancer and can easily adjust my schedule to suit yours. As for a “development plan”, if I were you, I would be very wary of anyone who gives you a development plan at this stage, before starting lessons or at least finding out about your level, speed of learning etc. as it differs from person to person.
If you feel you might be interested in using my services, I suggest we start and see how it goes. We can stop at any stage. Looking forward to working with you, kind regards, David
