Where could I sell amazon services

I have a question.
Where could I possibly sell amazon reviews?
I know how amazon sued some people but I'm not going large. I have few people with their own private amazon accounts who would like to make little money online ( we were writing reviews for few people and got paid 3$ BTC for it).
If someone could help I would appreciate it!

Possibly open up a fiverr, or create an amazon account and mass mail sellers directly?

I think that is too dangerous ATM and I think fiverr forbid anything like this as they are cooperating with amazon now
