Any boutique owners???

L

Can you give me some advice on owning your boutique? Where to start online, just any advice/tips! I work in a salon as a self employed barber, I booth rent. So I am going to start selling the clothes in the salon, but I would also like to make a FB page or something for people to buy from. I have my wholesale and resell license, and I have a few sites picked out where I am buying my products. I’m just kind of stuck on what else I need to do and how to get this started exactly.
