Anyone has a fabric retail store here?

I have a showroom plot of 100 gaj in a tier 3 city and planning to do fabric business.

I have some experience in this field but I have only dealt with clients online.

There's no fabric shop in our area, especially not the ones with quality material. I know I can bring that to the market here. But since no one in my family ever had any brick mortar shop, I am unsure how to go about it.

How do you even begin?

So let's say, I build the showroom in a year, get interior done. Should I arrange for the stock beforehand or what? Should I hire staff beforehand and start training them? How many will I need anyway?

Can someone guide me a bit with basic steps please?

I would really really appreciate help from someone who already owns a retail store.
