Hello!!
Your project has attracted my attention because I consider that my qualifications will fulfill your requirements.
I am a native Thai speaker, fluent in either English or Thai though. I am a new freelancer in this site but I have the experience in Teaching Thai to foreigners, besides I live locally BangNa area as well. I love teaching children, so would be pleased if I have the opportunity to teach your son.
Look forward to the opportunity to provide you with any further information that you may require. If you are interested, have any question or we could discuss the cost that suitable for you, please do not hesitate to contact me. Thank you.
Warmly regards
