Business em-mails proofreading

I've got an exciting project for anyone interested in proofreading :) My boss is looking for an editor/copywriter. Last year, he moved to the United States and has recently embarked on an exciting new business project.
Furthermore, he hopes to work as a teaching assistant at one of the universities.
This is to gain experience, with money being a secondary factor since he has his own company in Russia.

Looking for someone who can do:
*proofreading
*business writing
* email review
* turn content from boring to exciting

My boss contacts many professors and business people daily, and even though his English is fine, it is not good enough to communicate with professors or get a job in academia in the future.

Therefore, I would like to find a person who can "improve his English" in the emails, make business correspondence sound smart and sophisticated. My boss has a bs, ms, and mba, so it is crucial that from the emails you could see it (but please don't overdo it).

This job is for you if you are
1.Native English speaker (US)
2. Responsible
3. Accurate
4.
Have needed experience

If you are interested, please send me a before/after example (0,5-1 page long) of text that you "improved."
