Safe Review Swaps (kindle ebook amazon)

Looking for a VA who can do review swaps for books priced at $0.99 or $2.99, you must have experienced doing this and know how to get around amazons policies so reviews stick and are not removed. Will advanced the cost of purchase for books and will pay $2.50 per successful swap. If interested please let me know your experience and how many successful swaps you can do per month
