Validate AR e-commerce idea

https://beta.shop3dkart.com/ I am building my own AR e-commerce where brands can list their products and I will convert their product in 3D and add AR features for free in exchange for a small commission fee on per sale of the product. I need some suggestions regarding marketing. I will post my fully functional website in 1 week on LinkedIn, FB, Instagram but how to make it known throughout my target customers?
