I saw your post
I have created a website which would help you promote and sell your product
its helps any business present their products or services which they have offer.
You create your own store, which every product you add, generates your own mini catalogue.
Every single mini catalogue / store, that has a product added, pushes that product into our front facing catalogue so anyone can find what they are looking for fast.
We have not launched yet, but once we get a lot of businesses signing up and adding product, shoppers will come.

We will look to be running in about 4 weeks, but you could setup now as that functionality is available.
