I've been working as a VA in kindle book for more than a year now, I know every procedures and guidelines on how to avoid getting flagged. I'm also well adept in the system on how to promote books in the social medias and how to submit books in the websites. I can also give advice about my client books if the niche is good and I can also help in finding a good market to enter. I can provide my proof of working experience in this field if you're interested.
