I have over 3 years of experience working with Amazon SEO. Everything from reviews, feedback, votes, Q&A, purchases, downloads and much more. My personal Amazon account is a top 1,350 Reviewer Ranking at the moment. I also have a database of real individuals from all over the United States all with nicely aged Amazon accounts. They all have multiple purchases and reviews under their account. So I can offer all those services in bulk for your product(s).
Approach to the Job:
Based on the current situations for each product is how I'd approach each in helping to get them ranked higher. By providing verified reviews, seller feedback, then up voting all your 4 and 5 star reviews, and down voting all 3 star and below reviews to help push those down. Then asking Questions for you to then answer. Followed by getting your products on peoples wish/gift lists and listmania, then just basic purchases to help promote sales. All of this together really helps with product ranking, sales, and making that money. Here is a basic breakdown of pricing:
Non-Verified Reviews - $6/each, if you order 100+ I can do for $5/each
Verified Review - $7/each, if you order 100+ I can do for $6/each
Verified Review + Customer/Seller Feedback - $10/each, if you order 100+ I can do for $9/each
Up votes/Down votes - $11 for 60
Gift/Wish lists - $11 for 60
Purchases - $2/each
