Corporate Scarves

I have a new job (and no experience in this area, except on business development in corporate world) as a sales representative in a showroom for accessories, hats and gloves, scarves cold socks. What is the best way to get buyers into the showroom. I can not call all the buyers of the sale of other representatives have already and they are all the big dept stores. So where so I start (I have the book buyers) and how do I approach them. And how do I deal with buyers who never come into the showroom in New York

Wearing a t-shirt. Cold.
