I would like to buy amazon reviews and kindle book ranking

I have an ebook on kindle and it's review-less. I would really love to buy amazon reviews. Please Pm-me.
I release a lot of kindle books so if you are able to sell me reviews that stick (I did review exchanges in the past but the reviews disappeared after 2 months) for a reasonable price I will definitively become a consistent buyer

I'm also really interested in kindle book ranking services.
