Here is a copy of the letter that they wrote to me. I have taken off the name of my book. But yes, I can confirm that they do offer their own paid editorial services to the writers. Please make your own decisions after reading this:-
Thank you again for sending us your book. We think you have a very interesting idea and story premise. However, though we enjoyed many aspects of your book, we do not feel that it is quite ready to send to the publishers yet.
We think you have a great foundation, but we thought there could be work done on the dialogue and story development. We also thought that some of the action felt a bit contrived.
We suggest that you work with a professional editor and have a comprehensive overview/assessment done of your book, which would highlight the strengths and weaknesses, help with dialogue, action, showing/telling areas, characterization, timeline, story development, etc. The professional editor would be the best person to direct you on how to address these areas and bring your book to a more publishable standard.
If you are already working with a professional editor, we would be more than happy to read the next revision of your book!
If you do not already have an editor, Linda started Book Marketing International, which has an editing division. Here we are able to match authors with credible, professional editors who help authors bring their books to the next level. We continually use these editors because we trust their work, and we have one in mind who we think would be a great match for your book.
Either way, we are sorry we do not have better news, but we wish you the best in your literary endeavors. Please let us know if we can help further!
