I just finished my MA dissertation last week (a 15,000 word opus) and did another 15,000 word work for my BA (got a 1st for that). (I'm presuming by the word count that this is university level work?)
I've had excellent tutoring in academic writing and would love to help out. My background is in history (with lots of art and english thrown in), so as long as that doesn't rule me out due to lack of specialist knowledge :)
