@bullynj - I don't know about licensing in NJ, but my guess is that you don't need one. To get started with product, look into companies that have "affiliate" programs where you can use their sales material on your site and they pay you a commission. Set-up is usually pretty easy, you only have to hook-up some links on your site. Lots of people start this way.
Your success will depend on how well you can promote your site in the search engines which is the hard part.
