Grammatical structure and unnecessary “repetitive” text, and errors would need to be corrected

I am seeking a good (PhD standard) proof-reader whose mother language is British English and is experienced with academic writing at PhD level. My dissertation is completed and does not require too much work. However the grammatical structure and unnecessary “repetitive” text, and errors would need to be corrected. Excluding tables, figures, charts the, thesis is circa 80000 words and I need it done in 4 days from order agreement date. My budget is limited to £240 pounds as I am not working at the moment and am a full time student.

My PhD research subject is Reform of Commercial Property Leases (Property Law)
