Sergio of JCML has been invaluable to the long process of successfully posting my book on Amazon (and other distribution channels). Unlike many freelancers, he has taken a long-term perspective, protecting my interests at every juncture. Sergio is professional, prompt, smart, and loyal. I will definitely be calling on his expertise again. Highest rating. A+
