I reluctantly purchased marketing services for my book. (*Reluctantly* because I couldn't verify any services that this company had provided other then ghostwriting; but they assured me that they had social media and marketing experts.) I paid for a six month package. The services seemed OK in the beginning, but suddenly, after two months, there was nothing being done on my behalf. The project manager made several excuses but it was obvious that my money was not spent well. I can't speak to their ghostwriting services, but based on my experience, I recommend staying far away.
