Affiliate store not converting! Need help.

Hello everyone, I created an online store focusing on paintings, I did good keyword research (looked for a easy keyword to rank) and did moderate seo. Without much effort the website is 2nd on my country and 5th on the targeted country for a buying keyword related to paintings. I am getting more than 30 uniques per day but the website doesn't convert at all. (I know 30 uniques in not much, but it is a buying keyword and I am not looking to convert everyday, the sales give me from 20-100$ each, with 30 uniques I was looking to, at least, make a sale per month, which is not happening).

The main problems are:
--> The website is not in English language, but I am redirecting my traffic to a English store. (To fix this I thought about making my website a real store and outsource the paintings from the other website, would this be legal?)

--> I heard traffic outside the US doesn't convert as much, would this be a problem? What are some good ways to monetize traffic outside the US?

--> One other problem is that the website doesn't have enough content to be seen as authoritative, so people can be skeptic about buying from it, but I dont want to waste more time in this project if it will never convert, I have other projects that are profitable which I am happy to spend my time with if this is not going to convert well.

If you need to check out the website please pm me and I will send you the link.
