Marketing Consultant

I need this 25 page paper reviced with consistent grammer, corrected tense.

This paper was writing within four people, i need this paper to sound as if it was writing in one person.

This paper is very important to me, it would be sent out to a client of mine, and i want it to be done very efficiently with no mistake. 

I need this paper to be finished and revice within 2 hours.
