I would be glad to tackle this project for you!
If awarded, I will provide you with extensive proofreading, editing and re-writing experience. I will correct errors in grammar, syntax, spelling, and punctuation. I will also change passive and linking verbs to active whenever possible, correct unclear referents, and choose clear, interesting words throughout the letter. (I speak and write in US English as my primary language.)
Beyond this, I will re-write the letter in a compelling way that serves your purpose. I look forward to this opportunity to serve you!
