Anyone Help me look at Essay, Letter, and some other document for University Admission.

Hello, I need someone who has high quality writing English to look and fix my writing. It is include Essay, Letter, and other document (Fixing grammar) for the University admission that I am going to apply. Four things I need a help with for my essay: 1. Grammar & Proof Reading 2. If you think you want me to add or eliminate to make better essay. 3. It says I must write less than 3,000 words (including punctuation and space). But in Microsoft word says I wrote more than 6,000 words including space. Can you erase something you think it is unimportant as much as possible? 4. I would be happy if you can make the essay high quality of writing. I know I am bad writer because the vocabularies I used are all simple. Letter and other documents are just grammar checking and if you think you can develop some sentences, then it is okay too. Since I wrote all, but all you need to do is checking, I will say $80-90 is fair amount to check all these for me. Please bid if you are interested. Thanks,
