organization of sentences structure, English homework help

Hello my term paper is on the general fixed Operations of automotive dealerships. I have descriptions of what that is in my paper already- my problem is that it is a group paper and the consistency of my groups work is varying. There is everything from fully cited 90+ work to a lack of understanding of APA and basic citation.

needs to be 5000+ words

So what I need is a proof read and organization of sentences structure and additional information added to strengthen teammates parts. Going for an overall mark of a 90 needs to match up with the section on customer relationship management already in the report. Please add in text citations and fix references as well.
