Any good sources to utilize when writing/reviewing personal statements???

[Monkeys4Lyfe]

Title says it all. I have my first draft done but it definitely requires some work. Any free or inexpensive services I should take advantage of when review/rewriting?

I graduated college a while ago and my writing seems a bit rusty. Also, its a lot tougher than i thought to put my whole life into a page in a cohesive and significant way.

Thanks in advance.
