Answer - help???

Hello!
I've just finished writing a answer for a teacher in UK.
Any suggestions, comments, improvements, critiques, corrections (grammatical errors, or any misplaced words like 'the' and 'your' here and there) are highly appreciated.
here's the answer: "Sorry for the late reply. I was in the countryside with no internet access. I am extremely happy with your answer. My purpose of starting the phd studies with you between june/september of 2015 is because my oral communication in english is still not good enough to establish a conversation where I can clearly state my goals and abilities. Besides thats the time I need to finish my field research here in my country. I am currently attending private English lessons. I apologize I am not able for the interview now in September. So I ask you to talk in skype on december, period I believe to have improved my skills with the language. Looking forward to here from you. Thanks in advance"
