Hi there,
I can get your articles published on different blog sites with good Trust Flow, Domain Authority & Page Rank. To be honest I would like to tell you that freelancers fools their employers by providing links on High PR website, which in fact is of no use nowadays. What actually matters is the Trust Flow, Citation Flow & Domain Authority.
I just started working as a freelancer. Previously I used to handle SEO projects in my company and for an year I took care of Guest Posting, and that's how I earned the experience and built valuable links.
I can commit you to publish your 15 articles on various websites within 10 days. I don't know if the time I'm taking is more or less than the standard time taken by other freelancer, but if you're looking for good sites for publishing 15 articles, 7-10 days is the maximum time that should be taken.
Your valuable response is awaited.
Regards,
