Well with this service you can be annoyance free considering just that.
In this gig I offer to do following for you:
-Grammar check your article or any kind of textual document
-Ensure it meets the criteria of formality in case it is a business document
-Make sure that it follow all the rules,and uses colloquial and acceptable phrases
Not only will I grammar check your document but I will also make sure it meets other criteria such as formality or I will invite a degree of casualness into it.
