I'm not a very active user and of course, I'm not an expert. I used to run one store in the woman clothes niche (TERRIBLE IDEA THAT'S A VERY COMPETITIVE NICHE), very basic, with very cheap logo, a free theme. And dude that doesn't work but you need to start to learn something. Right now I have another niche store (Small niche), You need a professional but a really professional logo, not the things you can buy for 5 Bucks, a good theme, Good name (Brandable name), build your social networks (One of the best leads generator) I love Instagram (No fake followers, they will destroy the data that you can collect from Instagram and I never saw someone selling anything to bots).
No burn money on ads if you don't know what are you doing.
You need to build a good presence on the network before spending on ads. (What do you do when you a going to buy something from a Online Store? Personally, I Stalk Thems.)
Business is not easy, takes time and money,
No exist ANY method for easy money.
Small Instagram Guide for lead generation you are starting to keep it in your hands no bots, Upload max 2 - 3 pictures a day until you have at least 12 Publications, Follow - Unfollow is a good way to start (Start Slowly)(Good method is to follow - unfollow to people who likes the last photos in an Instagram account relative to your niche), Likes and Comments.
You need to read a lot more, but you already start that is great, Now you need to decide!. Do you want to keep trying because is hard?, if the answer is Yes, welcome this is a great world and in the long run is a good way to make money.
Apologize me for the bad English I'm not a native speaker.
