Punctuation

Hello, i just wrote a little statement of purpose for a university I worote everything and did a spell check but unfortunatly spell check does not fix the punctuation, and i am very bad in that field so I am searching the internet for a kind soul who would perhaps give it a quick read trough and ammend any mistakes i have made it is not long about 550 words or so and if someone would assist me i would be deeply gratful, i would rather email you that statement becouse it is a little personal and dont realy want everyone to read it, If anyone is willing to help a stranger i am eagarly waiting for a reply
