There are different types of editing services available to ebook authors. One type of editing will allow the editor to fix and rearrange your story. This type of editor actually have creative input into your work. This can be a beneficial service because you have a fresh set of eyes on your work. That being said, it is also a fairly expensive form of editing. Alternatively you can hire an editor to fix only your spelling and grammar. In the latter case you will have no creative input into your work but it will cost you substantially less. If you looked around you could probably find a spelling and grammar editor for about $2 per page.
