Proofreading of student's PS

Proofreading of student's Personal Statement, ~500 words in total.

I need to make sure that the text makes sense, has a balanced rhythm to it and there are no grammar errors. In case there are problems, you are not required to rewrite this, just merely point them out.

Since this is a tiny job really I am looking to pay around fiver, but I need it to be done today, 30th of June.
