I've set up The Fibonacci Murders (with its new cover and some corrections to the text) on Ingram Spark. Overall, I found the process very easy, comparable to the KDP and Nook Press process. However, you can set up both the print book and the ebook at the same time if you have the files ready.
After submission, they run the files through some automated validations. I was pleasantly surprised to find that they also have an actual human being look it over before releasing it. I'm not sure if any of the other services do this. I'm waiting on that process to be completed now.
I got the setup for free using their current promo code ("NANO"), which is good through the end of March. I'm hoping to complete True Death and Ice on the Bay before the promo expires.
