Hello,
I can help you with the necessary preparation.
1) You mentioned you live in New York, but do you intend to run the business as a proprietorship, LLC or LLP etc ? Please specify the structure of your business ? If a LLC, is it registered in NY or other state like Delaware ?
2) What products do you intend to sell ? Physical goods (e.g. books etc), or online goods (e.g. ebooks) or online services ?
3) Do you intend to sell only in the US (and territories), or world-wide or in specific countries ?
4) Do you intend to sell any products that are on the export restricted / watch list ? E.g. high-end night vision googles etc ?
5) Will there be any liabilities associated with the products ?
6) There are many more questions which I will provide once you answer these.
