Can someone please let me know which option I should prefer to get the illustration services for my book? I have recently completed writing a fiction novel and I want the cove of the book to have some ferocious animal illustrations as the novel is based on a horror novel. I am not sure whether I should get the animal illustrators for hire or should I hire a professional illustration company to get the illustration services. It will be a great help if anyone could help me out in making the right decision for taking the services. I will appreciate all the help you could provide.
