These would be curated pieces from individual artisans, so essentially I'm a reseller. Also, which usually comes first, an ecommerce store or the styling service?
Hone decor / furniture industry is one of the highest profit promising industry today. The profit margins on home decor ranges from 20% - 45% depend on the price of the product. If you're looking to get quickly popular, I suggest you start with the online store and promote it on offline as well. Keep the margins low initially so that you can attract more buyers. As the business grows, reinvest the amount back on the business so that you can stock more varieties.
All the very best.
