Dear Sir/Madam,
Since, I have designed and developed my own English Speaking course for 3 Indian languages, I have all the required skills and experience to complete your assignment with 100% accuracy. I have been teaching English since more than 26 years. So, proofreading is my Routine work. Without proper corrections, I don't give new lessons to my students. I check Spelling, punctuation, grammar, syntax, etc.
Therefore, I request you to kindly allot this work to me. I will give you 3 revisions, in-sha-Allah.
Thanking you,
Yours faithfully,
(Prof. Sheikh Yasin)
