We have a set of images for which we need 2000 different variations. Each set has 5 images and will be used as book covers. Each variation will consist of changing the text (book title) on each of the 5 images. We will provide the 5 images in PSD along with the required fonts. We will also refer you to a website where you can find the titles for all 2000 books. You'll simply change the text for each set, save it in the proper format and filename, zip and send to us.
To see the set of 5 images, please let us know and we'll send them to you.
