If I do business without NYS Vendor authorization (Sales Tax Authority) the fines are $500 a day.
As far as my list of retailers, I used a brand that I would like to hit the target market of and visited their website. I looked up all the stores in the area that carry them, and used that as a starting point. I called each one of them over the past month just to get the contact information so I can hit the ground running. I have spoken to a few just to gauge interest, but am held up.
I am focusing mainly on boutiques in trendy areas and the retail price of our shirts is $38, so street fairs is not where we are headed. There is one mrket we may buy a booth at, but we still need that tax number before we can do anything. Info on this place can be found here http://http://www.themarketnyc.com/flashmain.html
Hope this helps
