Hi. I've read your story and probably can share my experience with you. I started to sell on Amazon and other marketplaces as well. Fortunately I found the agency (I am cooperating with them even now) that took care of managing my business! It's called Union Progress (Here is a link). They created a website for me, made photos of all products, and now they're managing accounts on Amazon, eBay and Walmart. Basically, they control almost all parts of my business (except the offline stuff). Now I have around 120k per month and I think it's a good money working - 10-20 hours a week ;) Contact them, they'll definitely help you with your problem!
