Print ready designs in quark

We have done all the creative work for you--we need you to replace backrounds and make a few text and design changes on a book cover that we are printing. The book cover is part of a set. The other sets have been designed so you will work off the older designs in quark.
We need someone very professional who knows how to export files properly with crop, bleed, and in the right resolution for printing. This is not a creative job but it requires exactness, and experience.
