Selecting the right person to check that your novel is grammatically and semantically accurate is a tough call, as there are so many professionals who are willing to do this and to do it well.
The cost of providing this service will, therefore, be a hugely important criterion. Epworth Editing is likely to be the most cost effective route to your market audience simply because the work is being done for the love of seeing another aspiring author on their way to success and not for financial profit.
You have my contact details. It will cost you nothing, in the first instance, as I will happily look at a sample of your work at no expense to you. I will give you an honest assessment, very quickly, and if we both click, you will have my time and my experience. You will also have my complete involvement in your project because I only work with a very limited number of authors at any one time.
It is a great offer — for the right author. Is that person you?
