You just came back from a trip to India and your 500 digital photos are good but disorganized and need cropping and color correcting.  You face a daunting task.You know that you can use Photoshop or iPhoto and Shutterfly to create a super nice digital file and eventually a coffee table book.  But it means a big time investment in the process and in learning the latest software. For a few hundred dollars there are people in the third world who will do this for you. Completely custom and completed in a few days. Your opportunity as an entrepreneur is to bring these people together in a Uber kind of a way.
