I've worked with several writing services, and this is by far the best one. The quality of the work is always excellent, on time delivery and great communication. I never had such a great experience with Content Nucleus as I have with this one. I'm in the process of publishing my eBook and find this company to be excellent in customer service and in quality. I highly recommend them for any kind of writing work. Their designers provided some of the best cover designs for me and I am so glad to have found their services online. I am going to use them again in the near future.
