crazy7 I would probably suggest looking at reviews heavily before paying for any such service. As you probably know, any type of service like this could lead you to academic expulsion. Also, all the time you spend looking and reading reviews for this service could probably be used to write a rough draft at the very least!
However, I can't argue too much as I definitely used to write papers for friends in art school who were from out of the country. Looking back on it, it was a very risky thing to do! But, they did get A's and I got a free lunch so it (luckily) turned out okay.
