I've been using this for months now and they're pretty damn reliable. They deliver before the deadline and the quality is decent, if not the best. You will have to edit it on your own. They offer discounts too so use em. The support team are very prompt in replying and most of the writers are good but...
The reason I took out one star is because if these writers happen to find your email (which handmade usually does not reveal), they'll spam you with offers requesting you to get your work done through them and not through handmade. Even after my request to tell them to stop, they won't stop. So be careful with that
