What Services Should You Expect from Your Ghostwriter Besides Writing?

None.

Other services CAN be included, but no service besides writing should be expected.

If you are hoping for any kind of help besides the writing, you need to include that in a contract. Some ghostwriters have spent enough time in publishing that they have other talents or experience to help you along.

If your ghostwriter has experience in publishing, this could be important for you to tap into. You may get a sense of your writer's goodwill and know that you can rely on him/her to help you with that knowledge. But if you have any doubts and think you'll need that help, get it in the contract!

(And if you don't have any doubts, get it in the contract anyway. A writer of goodwill won't have any objection to including everything he'll provide.)

This is especially important if you're hiring a writer with the understanding that this person has publishing contacts. If you're expecting the manuscript to be set directly into someone's hands -- an editor's or an agent's, for example -- get that in the contract. That could be one of the most important things you're paying for!
