I will proofread anything in english

Yes, we can use either. We have also edited some documents in Australian style English.

Although we have various checkers switched on when proofreading we do not rely on these as they often are inaccurate. All of the work is checked manually by a native speaker of that language.

Normally, the answer is yes. we prefer to work in Word as that is the easiest way to see changes. we switch on Track Changes in the Review section. We can also work on online shared documents and you will be able to track via the programme.
