Hi,
This is Shubhangi here, I've been working as a content head since 7 years and have a good experience in this field.
I've written 2 eBooks in a week- one was SEO and the other one was Money Budgeting.
Both are on freelancer, you can check my reviews for it :)
I have an in-house team of 5 as well.
Our reviews tell a lot about our great services.
Regards
