It sounds like there's room for someone with appstore submission experience to offer a service with a faster turnaround and official submission guarantees (i.e., we'll review your app in a day, give you feedback, and if we say it's good and it gets rejected, we'll refund your money).
Anyone who can't navigate the submission process themselves, probably has a very low threshold for pain, and will likely not last very long doing business in the Appstore.
