Hello there,
We usually charge $1000 - $7000 for our different packages, but this is a small marketing task hence I am willing to do it for INR 10,000. Will research how the successful competitors are selling their ebooks and do the double work than what they are doing, and in time we will definitely see double success of what they are seeing. I have an SEO specialist in my team who can totally break down the algorithms of Amazon to understand how to get you ranked on their search engine and on Google as well.
Cheers!
Nayab K.
