We sell sustainable products for hikers and have been in local stores for years. For the last three months we have been on Amazon but we’ve only made a handful of sales. It’s only me and a partner, and most of our money is tied up in manufacturing, so we don’t have the money to hire someone to do this. We don’t know a lot about Amazon listing optimization and we would love to know how you successfully list your products on Amazon and sell them.
I don't think that businesses such as your will net out making money with Amazon. You will probably get lost in the shuffle and the deck is a lot larger than 52 cards. (An opinion)
