I personally don't think it's cheating, but I do think it's a waste of money. Do as Calc says, but don't just send it to one or two people, send it to as many trusted friends as you have. Sometimes it's difficult to send it to your friends and family. The statement to a degree bares your soul, but your friends and family are the people who you can really trust, and will give you good opinions. At least try that before dropping the big bucks on a writing service...unless of course you're lazy and can afford it, then by all means, give the writing service a try 🙂
