Think about the common mistakes that you make while writing and speaking. For example, I know of more than a hundred people who are more likely to say " I will have to REPEAT that AGAIN" rather than " I will have to REPEAT that!" These mistakes are common but not always overlooked! I am here to help you to read your script and perfect it beyond perfection!
I would be happy to proofread up to 1500 words fand also make improvisations if required
