I hate to be the bearer of bad news, but it is essentially impossible to succeed on ebay from Sri Lanka at the moment unless you actually have a unique product. Ebay is flooded with thousands of Sri Lankan sellers many drop shipping from China for a few weeks until that falls apart (it always falls apart). The others are largely selling local Sri Lankan products that have very little actual demand in America and the only sellers getting sales in those areas are selling at a loss in an attempt to somehow build business.
The things you are attempting to drop ship from China are available in our local stores for $1. They will not sell for $17 and if you were to actually sell one you would almost certainly end up having to refund the customer who thought they were purchasing the entire spread of items shown in your first photo, not the plastic plants available at their local dollar store.
