    I will certainly be working with Sergio at JCML Professional Services again. He was consistently professional, smart, prompt and resourceful as we navigated a path through distributors and online vendors. He is that rare freelancer who protects his clients' interests like they were his own.

    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+

    Sergio at JCML is one of those rare freelancers who treats your business like his own. He was prompt, thorough, pro-active, and thoughtful in all his dealings. He protected my interests as we navigated the world of Amazon ads and social media -- you could not have a better ally and colleague. Highest recommendation!!
